Embodiment Construction
[0039] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0040] Step 1: Read the first frame of image data and the position information [x, y, w, h] of the target block in the first frame of image, where x, y represent the horizontal and vertical coordinates of the target center, w, h represent the target width and height.
[0041] Step 2: Based on the target determination of the current frame image, extract the search area R centered on (x, y), use CNN to extract the convolution feature map, and upsample the feature map to the search area by bilateral interpolation method The size of R gets the convolutional feature map The size of R is M×N, M and N are width and height respectively, M=2w, N=2h, The size is M×N×D, D is the number of channels, l is the number of layers in the CNN, and its value is {37, 28, 19,} The present invention specifically uses VGGNet-19 as the CNN model.
[0042] Step 3: For the convolution...
