稀疏表达的夜间图像采集分辨率无关处理技术
An Independent Processing Technology of Night Image Acquisition Resolution Based on Sparse Representation
摘要
Abstract
In the image acquisition and 3D reconstruction,independent image resolution processing is needed to reduce the influence of il-lumination and environmental factors to the resolution. Therefore,an independent processing technology of night image acquisition resolu-tion is proposed based on the sparse expression. First the acquisition of night image is in wavelet denoising,conducting the curve segmen-tation of the shadow region and brightness region for night image. In the conditions of multiple color at night,the expression method of regularization of standardized sparse prior is used for the image equalization lock light processing,and image pixel traversal method for continuous uniform traversal of image blocks,realizing the shadow deviation compensation for acquisition image at night and independent resolution processing of that,solving the problem of image reconstruction caused by the resolution. The simulation results show that it can improve the imaging quality and resolution and the its peak signal-to-noise ratio and computing cost parameters are better than the tradi-tional method.关键词
