Geometry contrast enhancement for 3D point models using histogram modification
In this paper, we propose a geometry histogram modification algorithm to increase the visibility of 3D point models. We define a weak feature as a group of neighboring points yielding the small deviations of normal directions. Geometry histogram is defined as the distribution of the signed distance between a feature point and the locally approximated plane. We equalize and stretch the geometry ...
متن کاملLow-complexity Histogram Modification Algorithm for Contrast Enhancement
Histogram equalization is widely used in different ways to perform contrast enhancement in images. In this paper, a new Histogram modification algorithm is proposed for contrast enhancement of images. Histogram Equalization (HE) is one of the most popular technique used for digital image enhancement, but it is not suitable to be implemented directly in consumer electronics, such as television, ...

متن کاملInvertible Data Embedding By Histogram Modification and Contrast Enhancement
The main aim is to enhance the contrast of a host image by Reversible data hiding algorithm and to improve its visual quality. The highest two bins in the histogram are selected for data embedding so that histogram equalization can be performed by repeating the process. The Reversible data hiding algorithm is used for better preserving the visual quality of contrast enhanced image with increase...
متن کاملLocal Histogram Modification Based Contrast Enhancement with GPU Acceleration
─ This paper presents a novel local contrast enhancement algorithm based on local histogram modification. The computation of local contrast enhancement operators is usually slow though they produce better local contrast and details. We have addressed this issue by subtly designing a highly parallel algorithm, which could be easily implemented on Graphics Processing Units (GPU) to harvest high c...
