Embodiment
[0067] A method of determining the foreground image segmentation method and precision of the edges of the body in combination, comprising a main body determining process, a combination of both processes and process precision of an edge.
[0068] 1) determining the subject as follows:
[0069] 1.1) the input image using context-aware pyramid feature extraction module (the CPFE) for high-level multi-scale characteristic map, in order to obtain a rich context feature. (Which CPFE model for an existing model, are presented in CVPR2019 Conference). CPFE the VGG-16 network architecture Conv3-3, Conv4-3 and Conv5-3 as the basic high-level features, which VGG-16 is developed with Computer Vision Group at Oxford University researcher and Google's 16 layers deep convolution nerve network, VGG-16 comprises 13 layers convolution (convolutional five blocks, each block comprising convolution convolution layers 2-3) and three fully connected layers. Conv3-3 a third convolutional blocks inside th...
