  • superpixels.tar
    超像素就是把一幅原本是像素级(pixel-level)的图,划分成区域级(district-level)的图。可以将其看做是对基本信息进行的抽象(A superpixel is a plot of a pixel level, which is divided into a regional level. Think of it as an abstraction of basic information)

  • Matlab_based_DIC_code___Version_1___130814_EJ
    Digital Image Correlation (DIC) is an optical, non-contact method to measure full-field displacements and strains. The only requirement is that the test specimen has a random speckle pattern on its surface, either generated by the experimentalist (i.e. random paint pattern) or occurring naturally (i.e. surface texture at large magnifications). There is no inherent length scale to DIC - by choosing the appropriate magnification of images and the corresponding speckle size, DIC can be used to measure displacements from the meter scale to the micron scale.

    说明:  QR二维码识别中在对图像预处理后最重要的一步就是要进行定位,QR二维码中有三个位置探测图形,通过扫描其特征便可以进行精细定位,提出了一种新的算法用于筛选候选点。(In QR code recognition, the most important step after image preprocessing is to locate. There are three position detection patterns in QR code, which can be precisely located by scanning its features. A new algorithm is proposed to screen candidate points.)
