The code expects the image to be grayscale but it is RGB

在 MATLAB Online 中打开

 matchPic = imcropPolygon(bboxPolygon,videoFrame);
    matchPic = cutPic(matchPic);
    imwrite(matchPic,'test2.bmp','bmp');
    %load database at the beginning
    number = libCheck(load_database(5),imread('test2.bmp'));
 this is the code

Your a after reading the image is a 3D matrix. Say of size (m,n,3). In reshape you are using reshape(a,size(a,1)*size(a,2),1), this means you are suing only m*n numbers. Rest of the numbers (2*m*n) are missed, there fore this problem is arising. You have to see to it that a is a 2D matrix.

Either convert your image to gray or use a = a(:,:,1) ;
