代码说明:

  1.设计一个程序,对一幅灰度图像的实现如下几何变换,1)放大为原图1.5倍 2)绕中心旋转30度(CW) 3)采用偏移量插值实现一个透视变换. 灰度差值用最近邻插值和双线性插值 2. 绘制一幅灰度图像的梯度幅度图像(三点法求梯度),针对梯度幅度图像合理的选择一个阈值(通过试验即可)将其二值化,以获得图像边缘检测图像。 ((1) design a program, a grayscale image as geometric transformation, zoom 1) for 1.5 times the original 2) around the center of rotation of 30 degrees (CW) 3) interpolation of the offset to achieve a perspective transformation.gray level difference between the nearest neighbor interpolation and bilinear interpolation (2) draw a grayscale image of the gradient magnitude image (three-point method seeking gradient), the gradient magnitude image is reasonable to select a threshold value (the test can be) the second value to the image edge detection image.)

  • SURF-based-image-stitching
    SURF算法作为一种新近出现的特征提取方法,在重复度、独特性、鲁棒性3个方面,均超越或接近以往提出的同类方法,并在计算效率上具有明显的优势。本代码采用SURF算法检测图像并进行坐标变换与图像拼接。 采用SURF算法对图像进行检测,其主要是用Hessian矩阵对图像进行检测,对图像的特征提取之后找到图像的特征点。之后采用最近临快速匹配(NN)、随机抽样一致性(RANSAC)算法和最小二乘法参数优化(LM)对特征点进行提纯匹配。最后在两幅图像中进行坐标变换,达到统一坐标系和图像拼接的效果。 (SURF(Speeded Up Robust Features) as a method of feature extraction which newly appeared is over or nearly previous method on duplication, uniqueness, and robustness and have a clear advantage on computational efficiency. This code uses the SURF and coordinate transformation algorithm to detect image and image matching. This code uses the SURF algorithm of image detection, the main is to use the Hessian matrix of image for testing, to find the image after image feature extraction of feature points. After we used Nearest Neighbor (NN), Random Sample Consensus (RANSAC) algorithm and least square parameter optimization for purification of matching feature points. Coordinate transformation in the last two images, to coordinate system to achieve the same image stitching. )
