Fig. 1 is a schematic diagram of an application scenario of an image recognition method according to some embodiments of the present disclosure.
In the application scenario of FIG. 1, first, computing device 101 may receive a rigged image 102 submitted by a target user. Next, the computing device 101 may input the clothing image 102 into a pre-trained image recognition model 103, resulting in an image recognition result 104. Then, the computing device 101 may generate the prompt information 105 based on the image recognition result 104. Finally, the computing device 101 may send the aforementioned prompt information 105 to the audio-video device 106 associated with the aforementioned target user.
The computing device 101 may be hardware or software. When the computing device is hardware, it may be implemented as a distributed cluster composed of multiple servers or terminal devices, or may be implemented as a single server or a single terminal device. When the computing device is embodied as software, it may be installed in the hardware devices enumerated above. It may be implemented, for example, as multiple software or software modules to provide distributed services, or as a single software or software module. And is not particularly limited herein.
It should be understood that the number of computing devices in FIG. 1 is merely illustrative. There may be any number of computing devices, as implementation needs dictate.
With continued reference to fig. 2, a flow 200 of some embodiments of an image recognition method according to the present disclosure is shown. The method may be performed by the computing device 101 of fig. 1. The image recognition method comprises the following steps:
In some embodiments, the subject of execution of the image recognition method (e.g., computing device 101 shown in fig. 1) may receive the rigged image submitted by the target user via a wired connection or a wireless connection. Here, the target user may refer to a rider who is to dispatch the item. Here, the dressing image may refer to a front image of the rider.
In some embodiments, the executing subject may input the dressing image into a pre-trained image recognition model to obtain an image recognition result. Here, the image recognition model trained in advance may be a network model of various structures. For example, CNN (Convolutional Neural Networks), RNN (Recurrent Neural Networks), and the like. Of course, the model can be built according to actual needs.
In some optional implementations of some embodiments, the executing subject may input the dressing image into a pre-trained image recognition model to obtain an image recognition result. The image recognition model is generated by training through the following steps:
in a first step, a sample set is obtained. Wherein, the samples in the sample set comprise: a sample image and a sample label, said sample label comprising: sample name, sample category, and sample attribute value (sample category score value, higher sample category score value indicates higher degree of importance). For example, the sample may be [ xx.png, helmet, 10 points ].
And secondly, inputting a sample image included in at least one sample in the sample set into the initial neural network model to obtain an image identification result corresponding to each sample in the at least one sample. Wherein the image recognition result comprises: image name, image category, and image attribute value. Here, the initial Neural network model may be CNN (Convolutional Neural Networks) without model training.
And thirdly, determining the loss value of the at least one sample based on a preset loss function.
In some optional implementations of some embodiments, the third step may include the following sub-steps:
the method comprises a first substep of generating an image name score value and a sample name score value based on an image name included in an image recognition result corresponding to each sample in the at least one sample and a sample name included in the sample, and obtaining an image name score value group and a sample name score value group.
As an example, the image name score value may be a score when the image name included in the image recognition result corresponding to the sample is the same as the sample name included in the sample. Here, the score for the image name included in the image recognition result corresponding to the sample and the score for the sample name included in the sample being the same may be the same score value. The sample name score may be a score when the image name included in the image recognition result corresponding to the sample is different from the sample name included in the sample. In practice, first, vectorization processing may be performed on the image name included in the image recognition result corresponding to each of the at least one sample and the sample name included in the sample to generate an image name vector and a sample name vector, so as to obtain an image name vector group and a sample name vector group. And then, determining the association degree of each image name vector in the image name vector group and the sample name vector corresponding to the image name vector as a sample name scoring value to obtain a sample name scoring value group. Here, the vectorization process may be a one-hot encoding process. Here, the degree of association between vectors can be determined by the euclidean distance formula.
And a second substep of generating a class score value group based on the image class included in the image recognition result corresponding to each sample of the at least one sample and the sample class included in the sample.
As an example, first, the execution subject may perform vectorization processing on an image class included in the image recognition result corresponding to each sample of the at least one sample and a sample class included in the sample by using one-hot encoding to generate an image class vector and a sample class vector, respectively, so as to obtain an image class vector group and a sample class vector group. Then, the association degree between each image category vector of the image category vector group and the sample category vector corresponding to the image category vector may be determined as a category score value, so as to obtain a category score value group.
A third substep of determining a loss value of the at least one sample based on the at least one sample, the image recognition result corresponding to each of the at least one sample, the set of image name scores, the set of sample name scores, and the set of category scores.
Optionally, the loss value of the at least one sample is generated by a formula:
wherein the content of the first and second substances,
representing a loss value of the at least one sample,
the value of the initial loss is represented,
indicating the number of samples comprised by said at least one sample,
indicating the serial number of the sample in the at least one sample,
a preset boundary value is represented, and,
representing the second of said at least one sample
The value of the sample name score corresponding to each sample,
representing the second of said at least one sample
The image name score value corresponding to each sample,
a preset numerical value is represented, and,
representing the second of said at least one sample
The value of the category score corresponding to each sample,
represents the second of the at least one sample
The sample property values that an individual sample includes,
represents the second of the at least one sample
And the image attribute value included in the image identification result corresponding to each sample.
And fourthly, in response to the fact that the loss value is smaller than or equal to the preset threshold value, determining the initial neural network model as the image recognition model.
And fifthly, in response to the fact that the loss value is larger than the preset threshold value, network parameters of the initial neural network are adjusted, the unused samples are used for forming a sample set, the adjusted initial neural network is used as the initial neural network, and the processing steps are executed again.
The above formula and its related content are used as an inventive point of the embodiments of the present disclosure, and solve the technical problems mentioned in the background art, i.e., "it consumes more manpower to perform dressing verification, the verification efficiency is low, and a lot of time cost is consumed". The reason for the large time cost is often as follows: and more manpower is consumed for dressing verification, and verification efficiency is lower. If the above factors are solved, the effect of reducing time cost can be achieved. In order to achieve the effect, the loss function with the light weight is adopted in the method, and the loss calculation is carried out on the image name, the image category and the image attribute value of the dressing image by using two different light weights. Then, the obtained loss values are summed to obtain a total loss value. The generated total loss value can reach the designated threshold value in a short time, and the convergence speed of the model is further accelerated. Therefore, dressing verification speed is increased, and verification efficiency is improved. Further, the time cost consumption is reduced.
In some embodiments, the execution subject may determine feedback information corresponding to a preset image recognition result as the prompt information. For example, the image recognition result may be "the helmet is not worn right", and the feedback information may be "please wear the helmet right now, and take a picture again and upload the system".
And 204, sending the prompt information to the audio and video equipment associated with the target user.
In some embodiments, the execution subject may send the prompt message to an audio-video device associated with the target user. For example, the execution subject may send the prompt message "please wear the safety helmet immediately, and retake the picture and upload the system" to the mobile phone of the rider for the reference of the rider.
The above embodiments of the present disclosure have the following advantages: by the image identification method of some embodiments of the present disclosure, the consumption of time cost is reduced, and the accuracy of the audit result is improved. Specifically, the reason why the accuracy of the audit result is not high is that: the dressing verification method has the advantages that much manpower is consumed for dressing verification, the verification efficiency is low, a large amount of time cost is consumed, and meanwhile due to the fact that in the manual verification process, verification personnel have certain subjectivity, the verification result is possibly not accurate enough. Based on this, the image recognition method of some embodiments of the present disclosure, first, receives a dressing image submitted by a target user (rider). Thus, data support is provided for monitoring the rider's clothing. Next, the dressing image is input to an image recognition model trained in advance, and an image recognition result is obtained. Therefore, the dressing of the rider can be quickly checked and the dressing identification result of the rider can be quickly generated. Then, the presentation information may be generated based on the image recognition result. And finally, sending the prompt information to the audio and video equipment associated with the target user. Therefore, dressing verification can be rapidly carried out through the image recognition model, verification efficiency is improved, and time cost consumption is reduced. Meanwhile, the accuracy of the auditing result is improved.
With further reference to fig. 3, a flow 300 of further embodiments of an image recognition method according to the present disclosure is shown. The method may be performed by the computing device 101 of fig. 1. The image recognition method comprises the following steps:
In some embodiments, the specific implementation manner and technical effects of step 301 may refer to step 201 in those embodiments corresponding to fig. 2, and are not described herein again.
In some embodiments, referring to fig. 4, the executing subject may input the dressing image into a pre-trained image recognition model to obtain an image recognition result. Wherein, the image recognition model may include: a feature extraction network 401, a convolutional network 404, and a full connection layer 413, where the convolutional network 404 at least includes: first convolution layer 4041 and second convolution layer 4042. The execution subject may obtain the image recognition result by:
first, the dressing image may be input to the feature extraction network 401 to obtain an overall feature sequence 403 and a sub-feature sequence 402 of a target position in the overall feature sequence. The feature extraction network 401 may be configured to perform feature extraction on the clothing image. The feature extraction network 401 may be a BERT (Bidirectional Encoder representation from transforms) network. The feature extraction network 401 may also be a RoBERTa (Robustly Optimized BERT prediction Approach) network. Here, the target position may refer to a position where the user head sequence is located.
Second, the global signature sequence 403 is input into the first convolution layer 4041 and the second convolution layer 4042, respectively, to obtain a first signature sequence 405 and a second signature sequence 406.
Third, performing first pooling 407 on the first feature sequence 405 and the second feature sequence 406, respectively, to obtain a first pooled feature sequence set 409. Here, a first pooling process 407 may be used to perform feature compression and dimensionality reduction. The first pooling 407 may be an average pooling.
Fourth, a second pooling 408 is performed on the first feature sequence 405 and the second feature sequence 406, respectively, to obtain a second pooled feature sequence set 410. Here, a second pooling process 408 may be used to perform feature compression and dimensionality reduction. The second pooling process 408 described above may be a maximum pooling process.
And fifthly, generating a splicing characteristic sequence based on the first pooling characteristic sequence set, the second pooling characteristic sequence set and the sub-characteristic sequences.
In practice, the fifth step may include the following sub-steps:
in the first sub-step, each first pooled feature sequence in the first pooled feature sequence set 409 and the corresponding second pooled feature sequence are subjected to feature concatenation processing to generate sub-concatenation feature sequences, so as to obtain a sub-concatenation feature sequence set 411. Referring to fig. 5, the first pooled feature sequence set 409 may be [ [0.33, 0, 0, 0, 0], [0, 0.33, 0, 0, 0] ]. The second pooled feature sequence set 410 may be [ [1, 0, 0, 0, 0], [0, 1, 0, 0, 0] ]. The resulting set 411 of sub-splicing signature sequences may be [ [0.33, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0], [0, 0.33, 0, 0, 0, 0, 1, 0, 0, 0] ]
And a second sub-step of performing feature concatenation on the sub-feature sequence 402 and each sub-concatenation feature sequence in the sub-concatenation feature sequence set 411 to obtain a concatenation feature sequence 412. Referring to FIG. 6, the sub-signature sequence 402 can be [0, 0, 0, 0, 1 ]. The sub-splicing feature sequence set 411 may be [ [0.33, 0, 0, 0, 0, 1, 0, 0, 0, 0], [0, 0.33, 0, 0, 0, 0, 1, 0, 0, 0] ]. Thus, the concatenated feature sequence 412 resulting from feature concatenation can be [0, 0, 0, 0, 1, 0.33, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0.33, 0, 0, 0, 0, 0, 1, 0, 0, 0]
Sixthly, the splicing feature sequence 412 is input to the full connection layer 413, and an image recognition result 104 is obtained.
And step 304, sending the prompt information to the audio and video equipment associated with the target user.
In some embodiments, the specific implementation manner and technical effects of steps 303 and 304 may refer to steps 203 and 204 in the embodiments corresponding to fig. 2, which are not described herein again.
As can be seen from fig. 3, the flow 300 of the image recognition method in some embodiments corresponding to fig. 3 is compared to the description of some embodiments corresponding to fig. 2. First, a dressing image submitted by a target user is received. Thus, data support is provided for monitoring the rider's clothing. And then, the structure of the image recognition model is optimized, and the convolution network is used for carrying out convolution processing on the feature information extracted by the feature extraction network, so that more feature information is extracted, and the finally generated image recognition result is more accurate. Therefore, prompt information can be sent to the rider in time according to the image recognition result so as to remind the rider to correctly wear the safety protector and the like. Thereby improving the safety of the rider in delivering the article.
