Modified Panel Splitting Naturalness Preservation For Non- Uniform Illumination Images
نویسنده
چکیده
Image enhancement is an important tool for processing image. There exits many enhancement algorithms, in which Retinex algorithm enhance details of an image and is widely used. Retinex algorithm can remove illumination but cannot maintain the range of reflectance, hence it is not essential for non-uniform illumination images. So to preserve naturalness along with enhancing the details we propose an algorithm named naturalness preserved enhancement panel splitting algorithm. This paper mainly contributes three main issues. First, splitting a non-uniform illumination image into three coloured panels. Secondly, decomposing each and every image in the panel for brightness. Third, applying a bilog transformation to have a balance between the details and naturalness of an image. Experimental results for the proposed algorithm gives more enhanced naturalness preserved image. Keywords—FFT-transformation, NTSC, Restoration factor, Bi-log transformation, synthesis, MSR.

Non-uniform illumination endoscopic imaging enhancement via anti-degraded model and L1L2-based variational retinex
In this paper, we propose a novel image enhancement algorithm via anti-degraded model and L1L2-based variational retinex (AD-L1L2VR) for non-uniform illumination endoscopic images. Firstly, a haze-free endoscopic image is obtained by an anti-degraded model named dark channel prior (DCP). For getting a more accurate transmission map, it is refined by using a guided image filtering. Secondly, the...

Abstract: This study presents a novel image-naturalness restoration for the purpose of achieving better image quality with respect to the human visual system. Specifically, the authors suppress the artefacts around edges using image gradient components. They also appropriately enhance the image brightness using an adaptive gamma correction. In particular, they simply create a mapping curve to a...

متن کاملMission-critical monitoring based on surround suppression variational Retinex enhancement for non-uniform illumination images
In this letter, a surround suppression variational Retinex enhancement algorithm (SSVR) is proposed for non-uniform illumination images. Instead of a gradient module, a surround suppression mechanism is used to provide spatial information in order to constrain the total variation regularization strength of the illumination and reflectance. The proposed strategy preserves the boundary areas in t...
متن کاملFace Recognition in Non-Uniform Illumination Conditions Using Lighting Normalization and SVM
An efficient face recognition scheme is developed to recognize face in color images with non-uniform illumination conditions. The proposed scheme comprises two phases, namely face detection and face recognition. For the face detection phase, a lighting normalization function and an isosceles triangle approach are utilized to detect facial regions accurately. For the recognition phase, a SVM sch...
