基于蚁群算法的图像边缘检测

基于PCA的雷达点云数据的形状特征提取,主要是屋顶平面提取(The feature extraction of LiDAR point cloud data based on PCA)

说明：  对边缘图像作hough变换，从峰值中恢复出车道线(Right edge of the image for hough transform, recovered from a peak in the lane)

实现图像下采样，实现的采样方法有最邻近采样法、二次插值法、双三次卷积法。(Image sampling, the sampling method to achieve the nearest neighbor sampling method, the quadratic interpolation, bicubic convolution.)

求解l1范式的值，用于压缩感知中的稀疏表示。进行分类(Solving the value of l1 paradigm for compressed sensing of sparse representation. Classification)

MATLAB ICALAB FASTICA代码，挺难得的(The MATLAB FASTICA code, very rare)

说明：  比较硬阈值、软阈值法图像去噪，并提出折中阈值法去噪(Comparison of hard thresholding, soft thresholding image denoising, and put forward a compromise threshold denoising)

采用半隐式方案实现变分水平集图像分割方法(Active contour without edge, image segmentation)
