1.灰度变换:选择一幅对比度不足的图像,对该图像进行灰度变换,增强对比度,显示增强前、后的图像以及它们的灰度直方图。
2.直方图均衡:选择一幅灰度直方图不均匀的图像,对该图像进行直方图均衡处理,显示处理前、后的图像以及它们的灰度直方图。
3.选择一幅边缘较模糊的图像,利用高通滤波器(选择或自己设计)对该图像进行边缘增强,观察增强的效果。
4.选择一幅图像,叠加零均值高斯噪声,分别利用低通滤波器、维纳滤波器和中值滤波器对该有噪图像进行滤波,显示滤波后的图
像,比较各滤波器的滤波效果。
5.选择一幅图像,叠加椒盐噪声,分别利用低通滤波器、中值滤波器对该有噪图像进行滤波,显示滤波后的图像,比较各滤波器的
滤波效果。

使用迭代式阈值算法来提高图像对比度。可以指定某个色阶作为阈值,所有比阈值亮的像素转换为白色;而所有比阈值暗的像素转换为黑色。
(The use of iterative threshold algorithm to enhance image contrast. You can specify a color scale as the threshold, all pixels lighter than the threshold into white and all pixels darker than the threshold value is converted to black.)

BM3D
The Block-Matching and 3D Filtering (BM3D) algorithm is a computationally scalable algorithm based on this novel denoising strategy. It achieves state-of-the-art denoising performance in terms of both peak signal-to-noise ratio and subjective visual quality.

FMINSEARCHBND
Fminsearch does not admit bound constraints.
However simple transformation methods exist to
convert a bound constrained problem into an
unconstrained problem.
