Histogram Stretching in Digital Image Processing - Learn about histogram stretching techniques in digital image processing to enhance image contrast and improve visual quality.
Quantum image processingQuantum histogramQuantum computationQuantum softwareQuantum adder for superposition statesImage histogram is a simple but important concept in digital image processing. It is not changed with image translation, rotation, scale, and etc., which makes it be widely used in image ...

Digital image steganography survey and investigation (goal, assessment, method, development, and dataset) 3.2.1.4 Histogram Shifting (HS) The histogram shifting method in the spatial domain was first introduced by Ni et al. [217]. The idea is to set the lowest bin histogram and highest histogra...
Digital Image ProcessingImage Contrast EnhancementHistogram EqualizationBrightness Preserving EnhancementIn this paper, a simple modification to Global Histogram Equalization (GHE), a well known digitalimage enhancement method, has been proposed.

We are investigating histogram processing based image enhancement techniques to improve the ability of digital radiography (DR) for the detection of cardiac calcification. Computed tomography (CT) isdoi:10.1007/978-3-642-29305-4_246Chen, Xiang...
As you can clearly see from the images that the new image contrast has been enhanced and its histogram has also been equalized. There is also one important thing to be note here that during histogram equalization the overall shape of the histogram changes, where as in histogram stretching the...
