基于FPGA和DSP的红外图像预处理

mode purity method simulation

说明：  通过偏振进行图像处理和图像复原，利用大气光和物体反射光的光学模型进行复原(Image processing and restoration are carried out by polarization, and restoration is carried out by optical model of atmospheric light and object reflected light)

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.)

基于信息熵的迭代法求最佳阈值，并附参考论文及KSW熵法求阈值的程序。两个程序经实验测试通过无误。(Entropy-based iterative method for optimal threshold, together with reference papers and KSW entropy threshold method procedures. Two experimental test procedures correctly.)

自己编写的一个用于人脸识别2dpca程序，很好用的，里面有中文注释(I have written one for the face recognition 2dpca procedures, well used, which has Chinese Notes)

Visual C++ CAD应用程序开发技术源代码ch6(Visual C CAD application development technology source code ch6)

经过一系列步骤实现结构光的中心提取，结果还不错(After a series of steps, the center of structured light is extracted, and the result is not bad.)

说明：  视频转帧预处理 ，应用于红外图像序列处理，为后续处理提供便宜。(Video frame preprocessing, applied to infrared image sequence processing, provides cheaper for subsequent processing.)

说明：  IDL读取txt，txt第一列是纬度，第二列是经度，第三列是DN值， 坐标转行列号 ，并以图像的形式输出(IDL reads TXT. The first column of TXT is latitude, the second column is longitude, and the third column is DN value. The coordinate turns the line and column number and outputs it in the form of image)

说明：  基于MATLAB编程的菲涅耳离轴全息图的记录(Recording of Fresnel off-axis hologram)
