Computes average hash value of the input image

hash = cv.ImgHash.marrHildrethHash(img)
hash = cv.ImgHash.marrHildrethHash(img, 'OptionName',optionValue, ...)

Input

• img input image want to compute hash value, type should be uint8 with 1/3/4 channels.

Output

• hash Hash value of input, it will contain 16 hex decimal number, return type is uint8.

Options

• Alpha scale factor for marr wavelet. default 2
• Scale level of scale factor. default 1
