But the print function is used in python2 and the print() function is used in python3. What is %d %s in Python? Python uses the language C convention to format data. %d is used to format integer data and %s is used to format string data. GLCMs ( grey level co-occurrence matrics )s features are good for analyzing images with spatial variations without fixed objectiveness like seismic data. They are obtained by summing up all co-occurrences of grey scale values at a specifed offset (distance and angle in 2d case) over an image, with following aggregations.The iris detection and reorganization system using classification and glcm algorithm in machine learning. ...

GLCM Texture Features ¶ This example illustrates texture classification using texture classification using grey level co-occurrence matrices (GLCMs). A GLCM is a histogram of co-occurring greyscale values at a given offset over an image. In this example, samples of two different textures are extracted from an image: grassy areas and sky areas.It is time for final step, apply watershed. Then marker image will be modified. The boundary region will be marked with -1. markers = cv2.watershed(img,markers) img[markers == -1] = [255,0,0] See the result below.
