Abstract
The invention discloses a multitouch-based interactive video object segmentation fusion method. The multitouch-based interactive video object segmentation fusion method comprises the following specific steps: segmenting interested video object of a user from a start frame of a sequence through user interaction, that is, converting a touch signal sensed by a scanning system to contour line to express and giving the characteristic of an image space to the contour line; automatically tracking a video object defined by the user in subsequent frames of the sequence, that is, utilizing new information of each frame to update contour to be used for tracking the video objects; converting multipoint movement action into an instruction by a reprocessor through the processed contour line, the image space characteristic and pressure information, and transmitting the instruction to a main system so as to control panel display content, execute video object fusion and the like to achieve the effect of interactive video object segmentation fusion.
Description
Technical field
The present invention relates to a kind of Interactive Video Object Segmentation fusion method based on multi-point touch
Background technology
Video object segmentation grows up along with the production process of MPEG-4 standard.Since MPEG-4 standard formulation, the multimedia application based on MPEG-4 and MPEG-7 continues to bring out.In time in the past more than 10 years, proposed many video picture segmentation methods, but this technology is still ripe far away.
Manually participate in segmentation according to whether having, video picture segmentation method can be divided into two large classes: Interactive Video Object Segmentation and automatic video frequency Object Segmentation.From the angle of engineer applied, more actual and effective method is semi-automatic partition method at present, i.e. Interactive Video Object Segmentation.Interactive Video Object Segmentation algorithm is relevant with active contour model, the Video object segmentation algorithm grown up based on active contour model, need the manual reference mark selecting some around object outline, this mode can adopt multipoint-touch-technology.
Multi-point touch is the technology adopting human-computer interaction technology and hardware device jointly to realize, and can not have the man-machine interactive operation of carrying out computing machine under conventional input device.Multiple point touching technology, can form the man-machine interactive operation that a touch-screen can accept to carry out from point multiple on screen computing machine simultaneously.
The invention provides a kind of Interactive Video Object Segmentation fusion method based on multi-point touch, in the start frame of sequence, be partitioned into the interested object video of user by user interactions; User-defined object video is automatically followed the tracks of in the subsequent frame of sequence; Convert Multipoint movable action to instruction, and instruction is passed to main system and just can control Display panel content and perform the application such as object video fusion, reach the effect that Interactive Video Object Segmentation merges.
Summary of the invention
The object of the present invention is to provide a kind of Interactive Video Object Segmentation fusion method based on multi-point touch.The present invention includes following characteristics:
Invention technical scheme
Based on an Interactive Video Object Segmentation fusion method for multi-point touch, its concrete steps are as follows:
1) in the start frame of sequence, be partitioned into the interested object video of user by user interactions, specifically convert the touching signals that scanning system senses to outline line and represent, and give the feature of outline line image space;
2) in the subsequent frame of sequence, automatically follow the tracks of user-defined object video, specifically utilize the new information of each frame to do the renewal of profile, in order to follow the trail of object video;
3) outline line after process and image space feature and pressure information convert Multipoint movable action to instruction through reprocessor, and instruction is passed to main system and just can control Display panel content and perform the application such as object video fusion, reach the effect that Interactive Video Object Segmentation merges.
