Local enhancement using histogram statistics
Witryna15 maj 2024 · A method is described for the prediction of site-specific surface ground motion due to induced earthquakes occurring in predictable and well-defined source zones. The method is based on empirical Green’s functions (EGFs), determined using micro-earthquakes at sites where seismicity is being induced (e.g., hydraulic … WitrynaEdge-aware local contrast manipulation of images: localtonemap: Render HDR image for viewing while enhancing local contrast: histeq: Enhance contrast using histogram equalization: adapthisteq: Contrast-limited adaptive histogram equalization (CLAHE) imhistmatch: Adjust histogram of 2-D image to match histogram of reference image: …

Witryna28 sty 2024 · In Local histogram equalization (LHE), the algorithm is applied to a local group of pixels of the image. First of all, the image is divided into equal small regions that are known as tiles. Then the algorithm is applied to each tile, separately. This solves the problem phased by GHE. But it faces another problem. Witryna1 paź 2010 · Some other local methods that do not use histogram have been proposed in literature also.
