this looks murky, you're copying a CV_8U image to a CV_32F one:

img1.copyTo(Mat(img.rows, img.cols, CV_32F, blob.ptr((0, 0))));

i guess, you have to convert the input manually to float, before copying it:

img1 convertTo(img1, CV_32F);
img1.copyTo(Mat(img.rows, img.cols, CV_32F, blob.ptr((0, 0))));

or, even shorter:

img1 convertTo(Mat(img1.rows, img1.cols, CV_32F, blob.ptr((0, 0))), CV_32F);

this looks murky, you're copying a CV_8U image to a CV_32F one:
