摘要:Contrast enhancement based on multiscale decomposition of images has been proven to be a far versatile and efficient method than other regular techniques. We present here contrast image enhancement by using Laplacian Pyramid. Proposed method enhances the brightness and contrast of an input image by decomposing it into band pass image to improve both local and global contrast of an image. Laplacian Pyramid allows smooth enhancement of large images so that visible artifacts can be avoided that are seen when we apply histogram equalization (HE) technique alone.
