Title:
Enhanced Tonemapping Using LEP Filter, Multiscale Decomposition and Noise Reduction
Author Name:
Catherine Jose, and Neenu R.
Abstract:
Abstract A filter that does edge-preserving decomposition of an image is implemented here. It is containing the Local Edge Preserving (LEP) filter which has locally adaptive property. The filtered image contains local means everywhere and preserves local salient edges. Analysis has been done on the output of the method. A multiscale decomposition with this filter is implemented for manipulating a high dynamic range image, which consists of three detail layers and one base layer. An effective function is used for compressing the detail layers. A noise reduction, based on subband decomposition followed by separately filtering the LL subband with bilateral filter and other subbands with soft thresholding and then the subband synthesis, is applied on this LDR image as the HDR image that was the input to the system consists of noise. Keywords: LEP filter, Tone mapping, Noise reduction, HDR image, multiscale decomposition
