八个方向的sobel边缘检测算法

FPGA实现二维傅里叶变换，语言用的是VHDL,有仿真文件(FPGA to achieve two-dimensional Fourier transform, the language used is VHDL, there are simulation files.)

BMP和JPEG数据格式的图片读取与写入操作，有完整的代码(BMP and JPEG data format images read and write operations, complete code)

数字图像处理 小波处理 ，去噪音，比基于傅里叶变换的去噪方法好。 含噪信号经过预处理，然后利用小波变换把信号分解到各尺度中，在每一尺度下把属于噪声的小波系数去掉，保留并增强属于信号的小波系数，最后再经过小波逆变换恢复检测信号。(The noisy signal is pre-processed, then the signal is decomposed into different scales by wavelet transform. The wavelet coefficients belonging to noise are removed at each scale, and the wavelet coefficients belonging to the signal are retained and enhanced. Finally, the detected signal is restored by inverse wavelet transform. It is better than the denoising method based on Fourier transform.)

超声相控阵声场仿真程序，可以对相控阵探头的声场进行仿真(The ultrasonic phased array acoustic field simulation program can simulate the sound field of phased array probe)

自动种子区域生长代码，用MATLAB运行，不必选择种子点 可以自动选择阈值 实现图像分割(Automatic seeded region growing code, using MATLAB operation, do not need to select seed points can be automatically selected threshold image segmentation)

基于改进遗传算法的单阈值图像分割方法，该方法在基础遗传算法的基础上进行了改进(Application of Basic Genetic Algorithms in Image Segmentation)

H264的VERILOG代码,基本实现了全部的功能(H264 of the Verilog code, the basic realization of all the functions)

说明：  图像重建Matlab程序，仅供参考学习，希望对您有用。大家一起学习进步。(Image reconstruction matlab program, only for reference learning, hope to be useful to you. Let's learn and improve together.)

在图像边缘点上计算边缘法向量, Compute the norm vector at the boundary(compute the norm vector at the boundary)

检测图像中的轮廓，并定位坐标，可以对图片特征惊醒提取。(Detect the image contours, and position coordinates can be awakened picture feature extraction.)
