However, if the image is first converted to another color space, Lab color space, or HSL/HSV color space in particular, then the algorithm can be applied to the luminance or value channel without resulting in changes to the hue and saturation of the image. [5] There are several histogram equalization methods in 3D space.
OpenCV (Open Source Computer Vision Library) is a library of programming functions mainly for real-time computer vision. [2] Originally developed by Intel, it was later supported by Willow Garage, then Itseez (which was later acquired by Intel [3]). The library is cross-platform and licensed as free and open-source software under Apache License ...
Adaptive histogram equalization (AHE) is a computer image processing technique used to improve contrast in images. It differs from ordinary histogram equalization in the respect that the adaptive method computes several histograms, each corresponding to a distinct section of the image, and uses them to redistribute the lightness values of the image.

Bleachbit was used to erase emails on Hillary Clinton's private server during her time as Secretary of State during the Obama administration. [12]In August 2016, Republican U.S. Congressman Trey Gowdy announced that he had seen notes from the Federal Bureau of Investigation (FBI), taken during an investigation of Clinton's emails, that stated that her staff had used BleachBit in order to ...
The basic intent of the contrast enhancement technique is to adjust the local contrast in the image so as to bring out the clear regions or objects in the image . Low-contrast images often result from poor or non-uniform lighting conditions, a limited dynamic range of the imaging sensor , or improper settings of the lens aperture.
The form of the contrast transfer function determines the quality of real space image formation in the TEM. CTF Function prepared via web applet created by Jiang and Chiu, available at https://ctfsimulation.streamlit.app/ This is an example contrast transfer function. There are a number of things to note:
