摘要
提出了一种用于图像去噪、边界检测与图像特征增强的带时滞的非线性抛物方程模型,对此非线性抛物方程给出数值解法,并通过实验验证了新模型在有效去除噪声的同时也能较好地保存边界。
In this thesis,we prop ose a model of nonlinear parabolic equations with time-delay for image denoising,segmentation and image enhancing. Then,we use this model to do certain numerical experiments in image processing,which shows that this model can keep the image edge well when it denoises the image effectively.
