 # Image-Processing-Matlab
 Implementation of some functions like resize, rotate, histogram equalisation, adaptive histogram equalisation, histogram matching, bit plane slicing and tie point reconstruction from the image processing toolbox in Matlab.
 
-* **adaHist(img, ksize, clip)**: Returns adaptive histogram equalised **img** with kernel size, **ksize** and contrast clipped at **clip**. 
+* **adaHist(img, ksize, clip)**: Returns adaptive histogram equalised **img** with grid size, **ksize** and contrast clipped at **clip**. 
 
 * **bitPlanes(img, planes)**: Returns **img** reconstructed from planes in the **planes** list.
