摘要
为有效去噪,基于全变分及四阶偏微分方程图像去噪模型,提出一种图像综合去噪模型.该模型克服了全变分去噪模型带来的块效应以及四阶偏微分方程去噪模型在处理平滑区域时带来的不平坦现象.仿真结果表明,图像清晰度有了较大改善.
An integrated image denoising model was proposed based on total variation(TV) and the fourth-order partial differential equations(PDEs) denoising models to remove noises effectively.The model overcomes blocky effect which is inherent in the TV denoising model,while avoids the uneven phenomenon in the smooth region which is inherent in the improved fourth-order PDEs.Simulation results show that the fidelity of the image is improved a lot.
