Abstract
An interesting property of GCA (Gradient Correspondence Analysis) reordered pixels has been revealed. Pixels of gray level image are described by their gray level, by calculated gradient module and a family of calculated variables taking into account behavior of pixels’ modules in the neighborhood of the pixel. Evolved dataset is processed by GCA procedure and forms new ordering of pixels. Line chart for modules shows quills - lines consisting of pixels with the same values of the variables family. Pixels in the line chart for gray level lay along distinct curves and can be extracted with the aim of gradient module.
