Description

BACKGROUND OF THE INVENTION

The present invention relates generally to the field of image analysis, and more specifically to analyzing images to create workflows.
A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systemic organization of resources into processes that transform materials, provide services, or process information. In a broader sense, a workflow is a sequence of activities to be performed to complete a task. Each activity has a defined duration, actor, guideline, and other such details. The activities may also have parameters that indicate locations, timeframes, and other contextual parameters that impose limitations on the occurrence of said activities. Workflows can provide instructions for task completion to an individual who is unfamiliar with either the task itself or a context in which the task must be completed.

SUMMARY

As disclosed herein, a computer implemented method for generating contextual workflows includes receiving a plurality of images, analyzing the received plurality of images to identify one or more activities corresponding to each image and one or more contextual details corresponding to each image, wherein the contextual details indicate a capture location, a capture time, a capture sequence, or a capture subject for each of the images, calculating a confidence weighting for the one or more identified activities for the plurality of images, creating a contextual workflow according to the calculated confidence weightings, receiving a query for a workflow corresponding to an indicated context, and identifying one or more workflows that matches the indicated context. A computer program product and a computer system corresponding to the method are also disclosed.

DETAILED DESCRIPTION

When engaging in unfamiliar activities, a person may not know the correct sequence to take in completing said activities, if there is one. For example, a person who has traveled to an unfamiliar location may be unaware of a customary sequence of events taken with respect to a particular activity. While in some cases prior research can provide some information, such research may not take into consideration existing contextual details, such as a time of day, time of year, nearby objects, or events. Furthermore, prior research may be infeasible with limited time, especially if one is put into a situation unexpectedly or without prior planning.
For example, if visiting Boston and trying to take the subway, a person may not know that at certain times of day at some platforms, he must stand in specific spots or else they may miss the train or must rush to try to board. The present invention analyzes images that correspond to one or more contextual details related to a device's current conditions to provide one or more workflows indicating suggested actions based on the activities displayed in the images. In the above example, the present invention analyzes images taken at the current time of day of the subway platform the person is standing at, and identifies that people who are standing in certain locations are in said locations before and after the arrival of the train. In other words, these people were unable to board, perhaps because it is a particularly busy time for this platform and they were standing too far from the doors. A workflow is therefore created indicating that the user needs to stand in a certain location to board the train (next to a pillar, away from a stairwell, etc.).
The present invention will now be described in detail with reference to the Figures. Implementation of embodiments of the invention may take a variety of forms, and exemplary implementation details are discussed subsequently with reference to the Figures.
FIG. 1 is a functional block diagram depicting one example of a contextual workflow creation system 100 in accordance with one embodiment of the present invention. As depicted, contextual workflow creation system 100 includes computing systems 110 and network 130. Contextual workflow creation system 100 enables workflows to be created and identified based on a set of one or more contextual details.
Computing systems 110 can be desktop computers, laptop computers, specialized computer servers, or any other computer systems known in the art. In some embodiments, computing systems 110 represent computer systems utilizing clustered computers and components to act as a single pool of seamless resources. In general, computing systems 110 are representative of any electronic devices, or combinations of electronic devices, capable of executing machine-readable program instructions, as described in greater detail with regard to FIG. 5.
As depicted, computing system 110B includes a context detection application 116. Context detection application 116 may be configured to detect one or more current contextual conditions corresponding to computing system 110B. Example contextual conditions may include a current time, location, or weather conditions detected by computing system 110B, or a current event indicated by a calendar service or social networking platform available via computing system 110B. In some embodiments, context detection application 116 is further configured to capture, store, and provide images to computing system 110A via network 130.
As depicted, computing system 110A includes a workload creation application 112. Workload creation application 112 may be configured to receive images as well as current contextual conditions corresponding to computing system 110B. In some embodiments, workload creation application 112 is configured to execute a workload creation method. One example of a suitable workload creation method is described in further detail with respect to FIG. 2.
Network 130 can be, for example, a local area network (LAN), a wide area network (WAN) such as the Internet, or a combination of the two, and include wired, wireless, or fiber optic connections. In general, network 130 can be any combination of connections and protocols that will support communications between computing system 110A and 110B in accordance with an embodiment of the present invention. In at least one embodiment of the present invention, network 130 transmits contextual details and identified workflows between computing system 110A and 110B.
FIG. 2 is a flowchart depicting a workflow creation method 200 in accordance with at least one embodiment of the present invention. As depicted, workflow creation method 200 includes identifying (210) one or more stored images, identifying (220) one or more images and one or more contextual details corresponding to the one or more images, calculating (230) a confidence weighting for the one or more identified activities, creating (240) a context workflow according to the confidence weightings, receiving (250) a query for a workflow corresponding to an indicated context, identifying (260) one or more workflows that matches the indicated context, and transmitting (270) the at least one matched context workflow. Workflow creation method 200 enables the creation and identification of appropriate workflows according to one or more contextual details.
Identifying (210) one or more images of interest may include receiving one or more images from a user device. In some embodiments, the user device provides one or more stored images from its own local storage. In other embodiments, the user device provides the one or more stored images by providing location details for the one or more stored images corresponding to an image hosting platform, photo sharing service, social network platform, or other platform on which photos are stored or shared. The one or more stored images may correspond to photos or video content from which still images can be extracted. Identifying (210) one or more stored images may further include receiving a set of images as well as an indicator indicating one or more stored images of interest. The indicator may indicate specific images to be analyzed, or may indicate image formats or other image details used to identify the one or more stored images of interest. For example, the indicator may indicate that only JPEG files at a particular storage location are to be analyzed.
Detecting (220) one or more contextual details corresponding to the one or more images may include analyzing each of the one or more images to identify one or more contextual details corresponding to each image. In some embodiments, each image of the one or more images of interest may be analyzed to identify any of a time context, a location context, an object context, or an event context. A time context corresponds to the date and time at which the image was created.
An object context corresponds to one or more objects that are detected within an image. Existing object recognition techniques may be used to identify any objects that appear in an image. Utilized object recognition techniques may include, but are not limited to, appearance-based methods (such as edge matching or greyscale matching), feature based methods (such as interpretation trees or pose clustering), gradient histograms, and template matching. In at least one embodiment, an indicator provides a maximum number of objects to be analyzed or identified in each image to minimize processing time. For example, an image can contain hundreds of objects, but an indicator may indicate that only the ten most prominent objects are to be analyzed and considered to provide an object context. In such cases, the provided object context is effectively a list of the ten most prominent objects in each image.
A location context corresponds to a location at which the image was created. In some embodiments, the location context corresponds to GPS information available via a device taking a photo at the time the photo was taken. In other embodiments, the location context corresponds to a location pictured in an image. For example, consider an image taken at coordinates (X,Y) facing north that displays a barn in the image. A second image taken at the same coordinates (X,Y) facing south does not display the barn, and therefore may not be considered to be the same location as the first image because of the contents of the image. The object recognition techniques discussed previously may also be used to provide location contexts of this nature.
An event context is an event to which an image corresponds, and may be determined according to a number of factors. In at least some embodiments, an event context may be determined by analyzing the time context, the object context, and the location context, along with other available information. For example, consider a set of images taken on April 10^thbetween 2 PM and 6 PM. The image locations all correspond to a restaurant, and the object identification results from the image analysis reveal that the most prominently featured objects in the set of images are a birthday cake, a banner reading “Happy Birthday,” a pile of gifts on a table, and a group of individuals. Processing calendar information provided by a user indicates that April 10^this individual A's birthday. Aggregating all of this information would provide an event context for the set of images, indicating that they correspond to a birthday party for individual A. In other embodiments, an event context may be identified according to an image's source location, such as the website it is from or the title of an album the photo is in.
Calculating (230) a confidence weighting for the one or more identified activities may include determining a sequence corresponding to the images. In at least one embodiment, calculating (230) a confidence weighting includes using existing image analysis techniques identifying one or more objects, activities, or locations depicted in each of the images. A confidence weighting corresponding to the likely sequencing of the identified objects or activities is then calculated. In one embodiment, the confidence weighting is based on available timestamp information corresponding to each of the images depicting an activity or object. Because all of the images may not suggest the same sequence of activities, the confidence weightings indicate how many (or what percentage) of the images suggest or indicate a particular sequence for the activities.
The confidence weighting for an activity may additionally be based on how frequently said activity appears in an image cluster. In such embodiments, a lower selected threshold “X” (wherein X is a percentage or a ratio) may be implemented to define that any activities that appear less frequently than the selected threshold “X” are to be excluded from a created workflow. Additionally, a selected optional threshold range may be implemented to define that any activity for which a corresponding appearance frequency falls within the selected optional threshold range will be included as an optional step in a created workflow. Consider an example where a set of images includes seven image clusters related to attending a theme park, and where a selected lower threshold is 0.5, and a selected optional threshold range is (0.5, 0.6). Six of the clusters include images of people standing in a ticket queue, five of the clusters include images of people entering a gate, all seven clusters include images of people on a ride, four of the clusters include images of groups of people posing, and one of the clusters includes an image of a bird sitting on a tree branch. In such an example, the confidence weighting may be calculated according to what percentage of the clusters include an image of each activity. Based on these weightings, it may be determined that taking a group photo is an optional step since just over half of the image clusters include such an image, and the image of the bird (and an identified corresponding activity such as “birdwatching”) may be disregarded when creating a workflow because its confidence weighting is below the selected threshold.
Creating (240) a context workflow according to the confidence weightings may include analyzing the calculated confidence weightings for the one or more identified activities. The context workflow may be created according to the most likely sequence of activities as indicated by the calculated confidence weightings. In one embodiment, creating the workflows further includes saving the created workflow as a workflow file. In such an embodiment, the workflow file may be stored in a workflow database. The workflow file may contain the workflow itself, as well as one or more data fields indicating contextual details corresponding to the created workflow. For example, the data fields may indicate that the workflow corresponds to locations X and Y and event Z. These data fields enable simplified query execution by enabling the contextual details of each workflow to be quickly identified in response to a query.
Receiving (250) a query for a workflow corresponding to an indicated context may include receiving a user-initiated query for a workflow corresponding to a set of indicated contextual details. The received query may include details corresponding to any number of available contexts. For example, the query may request workflows that include a specific location, or may request workflows that include a specific location, a specific time, and a specific event context. Additionally, the received query may indicate further limitation requirements for the workflows. For example, a query may request a workflow that begins or ends at a specific location. In other words, the query may impose sequence limitations on the workflows in addition to contextual limitations. In at least one embodiment, the received query corresponds to a device's active contextual details. In other words, the query is executed to identify workflows corresponding to the device's current conditions, such as its current location and the current time.
Identifying (260) one or more workflows that matches the indicated context may include searching one or more workflow files to identify one or more workflows that match the limitations imposed by the query. In one embodiment, identifying (260) one or more workflows that matches the indicated context includes analyzing the context data fields of one or more workflow files to identify any files that contain a workflow corresponding to the indicated context. For example, if a query for workflows corresponding to location X is executed, application 112 may analyze each workflow file to determine whether said workflow file's context data fields indicate that the workflow corresponds to location X at any point.
Transmitting (270) the at least one matched context workflow may include providing the identified one or more workflows to a device from which the query was received. In one embodiment, only workflows that match all contexts indicated by the received query are transmitted. In other embodiments, workflows that match all contexts are transmitted when available, but workflows that match the most indicated contexts may be provided in the absence of a workflow that meets all the requirements.
FIG. 3A depicts an example set of images 300 in accordance with one embodiment of the present invention. As depicted, the set of images 300 is divided into four image clusters 310, wherein each cluster comprises a plurality of images (depicted by shaded squares, wherein the shading indicates which cluster each image belongs to). The images are positioned according to the location on which the image is focused. The clusters are then created according to shared locations of focus in the images. As depicted, some of the images are not included in a cluster, as these images are not directed towards one of the locations corresponding to the four clusters.
FIG. 3B depicts an example table 320 indicating the contextual details to which each cluster of images 310 from FIG. 3A corresponds. As depicted, cluster 310A corresponds to images directed towards location A, taken at 18:00, and the images include people removing their shoes. Cluster 310B corresponds to location B, taken at 18:15, and the images include people standing in a queue. Cluster 310C corresponds to location C, taken at 18:30, and the images include people washing their feet under a water tap. Cluster 310D corresponds to location D, taken at 18:40, and the images include people eating a meal at a group of tables. In this example, the time indicated in the table corresponds to an average capture time for all of the images in the cluster. This average capture time is used to indicate a sequence in which the events indicated by the images typically occur. In another embodiment, the range of existing capture times may be used to determine sequencing as opposed to the average capture time.
FIG. 4 depicts an example created workflow 400 in accordance with one embodiment of the present invention. Workflow 400 corresponds to the set of images depicted and discussed with respect to FIG. 3A and FIG. 3B. As depicted, workflow 400 includes removing (410) shoes at location A between 17:50 and 18:10, standing (420) in line at location B between 18:05 and 18:30, washing (430) feet under a tap at location C between 18:20 and 18:50, and eating (440) a meal at a group of tables at location D between 18:30 and 19:00. In this embodiment, the timestamp guidelines are created according to the range of times in which images corresponding to each activity were captured.
