Brightness/contrast adjustment the implementation details of this block vary significantly, but the key goal is to enhance image contrast and digitally adjust image brightness. Typical contrast enhancement algorithms would include histogram stretch, histogram equalization, local and global contrast adjustment ...
An image processing method for the adjustment of photographic contrast which utilizes a user interface to display digital image data captured by an image processing apparatus, and allows the user to adjust the set value of the image data and then to store this adjusted value in a parameter setti...
Second, we propose to identify the composite image created by enforcing contrast adjustment on either one or both source regions. The positions of detected blockwise peak/gap bins are clustered for recognizing the contrast enhancement mappings applied to different source regions. The consistency between...

(CDR).Pixel value distributions were measured for various tissue thicknesses of a dental quality assurance jaw phantom and the average pixel values and SNR calculated.Equalization resulted in enhanced image contrast of underexposed images by effecting pixel value adjustment with little change in SNR. ...
Then the bilateral tone adjustment technique is used to improve the image quality. BiTA is applied to the luminance, while the color saliency detector calculates the amount of saliency of each pixel with respect to neighbourhood. Saliency produces a saliency map with well defined boundary of ...
