Consider an image whose pixel values are confined to some specific range of values only. Then each of these blocks are histogram equalized as usual. For example, below image shows an input image and its result after global histogram equalization. This normally improves the contrast of the image. matlab. uicontrol BUCHE DELICE DE BOURGOGNE/CITRON 6 - 8 PERSONNES. Based on your location, we recommend that you select: .
