They are extracted from open source Python projects. The tilde (~) in front of the transform indicates that we're going from x,y to col,row, instead of col,row to x,y. This enables reading and writing files with more dimensions than just x, y, layer, and time. The pixel's center is returned by default, but a corner can be returned by setting offset to one of ul, ur, ll, lr. 按照osg,x,y,z来说,我猜是地心直角坐标系。 但是这个坐标系很不直观。 高中学的三角函数都还给老师了,有没有人给我一个现成的坐标转换矩阵。. affine # col, row to x, y x, y = a * (col, row) # x, y to col, row col, row = ~a * (x, y) Clean, nice looking code that's harder to get wrong, wouldn't you agree? And as @Asgerpetersen pointed out , if there were a non-zero rotation parameter, the affine example would handle it seamlessly while the. A dataset’s transform is an affine transformation matrix that maps pixel locations in (row, col) coordinates to (x, y) spatial positions. Unlike MSE, the SSIM value can vary between -1 and 1, where 1 indicates perfect similarity. as an ndarray. NET side then use the table variable as an in clause an Nick has said.
