摘要:
A method for block truncation-type compressed domain image processing. Image data is received. Block truncation compression (BTC) is performed on the image data to generate a compressed representation of the image data. The broken pixel representation is enhanced in a compressed domain.

摘要:
This invention provides a method for automated image enhancement. Attribute measurements are extracted from a digital image and used for the generation of at least a noise threshold parameter, a sharpness parameter and a radicality parameter. The noise threshold parameter and sharpness parameter are evaluated to determine the degree of noise reduction and the degree of sharpening to be performed, collectively a determined enhancement. The determined enhancement is applied to derive a nominally enhanced image. With respect to the radicality parameter, the output image is the weighted average between the initial image and the nominally enhanced image.
