Image processing is the method of processing data in the form of an image. Image processing is not just the processing of image but also the processing of any data as an image. It provides security.

Image Processing classify as three type.

(1) Low level image processing (noise removal, image sharpening, contrast enhancement)

(2) Mid level image processing (segmentation)

(3) High level image processing (analysis based on output of segmentation)

In electrical engineering and computer science, analog image processing is any image processing task conducted on two-dimensional analog signals by analog means (as opposed to digital image processing).

The signal processing hardware can be used for image processing also. DSP processors like TMS 6713 can be used in image processing also. The hardware is required for image capture also.
