[0096] Step 1: Input the original image
[0097] Input the original image into the reimbursement receipt image segmentation system.
[0098] Step 2: Feature marker positioning
[0099] There are a variety of feature marks on the original image, including blue train tickets [1], red train tickets [2], printed oval stamps [3], two-dimensional codes [4], round stamps on the back cover [5], back cover Fangzhang [6] and other six categories. pass image 3 The fully convolutional neural network (FCN) shown is a UNet structure, down-sampled for feature extraction, then up-sampled to gradually fuse the feature information of each scale, and finally output the predicted feature score map, extracting 7 predictions Figure scoresmap, the value range of each scoresmap is between [0,1], the 0th scoresmap is the background of the original image. Then, for each scoresmap image, the pixel whose score is greater than the first set threshold (0.5) is considered to be a feature marker pixel, ...
