A method of processing an image is disclosed. The method comprises obtaining an image decomposed into a set of scaled images, each being characterized by a different image-scale; and calculating, for each of at least some scaled images, a relative luminance between the scaled image and another scaled image of the set, using intensities in the scaled image and intensities in the another scaled image. The method further comprises processing each scaled image using an adaptation procedure featuring an image-specific effective saturation function of the relative luminance, thereby providing a processed scaled image; combining at least some of the processed scaled images to provide a combined image; and outputting the combined image to a computer readable medium.

Method and system for processing an image featuring multiple scales

A method of processing an image having a plurality of picture-elements is disclosed. The method comprises: preprocessing the image to selectively enhance contrast of some picture-elements of the image, and employing a companding procedure for the preprocessed image, thereby providing a processed image. The contrast enhancement optionally and preferably features a mapping function having a plateau region for diminishing image data with intensity levels below an intensity threshold, thereby providing a preprocessed image.

Method and system for processing an image

A method of processing a polychromatic image is disclosed. The method comprises, for each of at least a portion of the picture elements, assigning to the picture element a new color value for each individual color, and storing the new values in a computer readable medium. The new values are assigned by: processing each of a first and a second colors of the picture element, based, at least in part on first and second colors of peripheral picture elements, to respectively provide a first processed color value and a second processed color value; employing optimization for reducing error and for assigning to the picture element a new color value for each of the first and second colors; and assigning to the picture element a new color value for a third color calculated based, at least in part, on the new color values for the first and second colors.

Method and system for reducing chromatic aberration

A method of processing a computerized tomography image is disclosed. The method comprises preprocessing the image using contrast enhancement weight function, thereby providing a preprocessed image having a first dynamic range; and applying a companding procedure to the preprocessed image, so as to reduce the first dynamic range.
