B正在做一个关于图像理解方面的研究，她的目标是识别图像中的轮廓。当前阶段，她希望能够识别正方形。图像用一个矩阵表示，矩阵的每个元素对应于图像中的一个像素点，值为0或1，0表示背景，1表示前景。需要寻找的正方形必须满足线宽为单像素，且大小至少为2x2。她希望你能帮她找出图像中满足如下条件的两类正方形的个数：
正方形的边与矩阵边缘平行；
正方形的边与矩阵对角线平行；(B is doing a research on image understanding, and her goal is to identify the outline in the image. At this stage, she wants to be able to identify the square. The image is represented by a matrix. Each element of the matrix corresponds to a pixel in the image, with a value of 0 or 1, 0 for the background and 1 for the foreground. The squares to be searched must meet the line width of a single pixel, and the size is at least 2x2. She wants you to help her find the number of two types of squares in the image that meet the following conditions:
The edge of a square is parallel to the edge of a matrix.
The edge of a square is parallel to the diagonal of the matrix;)
