CAPTCHA - Wikipedia, the free encyclopedia
CAPTCHAFrom Wikipedia, the free encyclopediaJump to: navigation, search Early CAPTCHAs such as these, generated by the EZ-Gimpy program, were used on Yahoo!. However, technology was developed to read this type of CAPTCHA[1] A modern CAPTCHA, rather than attempting to create a distorted background and high levels of warping on the text, might focus on making segmentation difficult by adding an angled line Another way to make segmentation difficult is to crowd symbols together. This is Yahoo!'s current CAP... (more)

Free Mind » CV 课程 Project：简单验证码的识别

Free Mind » CV 课程 Project：简单验证码的识别
验证码的识别可以说是一个非常困难的问题，更何况现在有一些验证码让人来辨认都有些不容易，当然正如我标题里说的，我这里讨论的是一种简单的验证码，具体来说就是经过旋转、缩放之后再加上一些随机线条作为干扰而得到的图片，如右图所示。其实这个问题最开始是 MSTC 第四届趣味程序设计竞赛中的一道题，这个学期上了一门《计算机视觉》课，最后要求交一个 Project ，老师给了一些题目，也可以自己想主题，于是我就定了这个主题。 由于最近各种 deadline ，我也没空把详细过程再用 blog 的方式写一遍了，如果感兴趣可以直接看我的 Report 文档以及完整的代码。 其实这个问题我在当时趣味程序设计竞赛的时候就尝试解决过，不过我当时用的办法是 PCA ，事实上，我尝试了 PCA 、LPP 以及 NPE ，从各种 paper 上还有理论推导中的道理来看，似乎都是后两者要更加先进一些，然而结果却是 PCA 最好，当时就令我有些诧异。其实我一直以来都有一些极端的“理想”，就是总希望有那么一些非常“自动化”或者“傻瓜化”的方法，把问题放进去就能得出结果，例如我在中学的时候凡是遇到几何题，几乎都是首先尝试建立坐标系用解析...

Segmentation (image processing) - Wikipedia, the free encyclopedia
Segmentation (image processing)From Wikipedia, the free encyclopediaJump to: navigation, search In computer vision, segmentation refers to the process of partitioning a digital image into multiple segments (sets of pixels) (Also known as superpixels). The goal of segmentation is to simplify and/or change the representation of an image into something that is more meaningful and easier to analyze.[1] Image segmentation is typically used to locate objects and boundaries (lines, curves, etc.) in images.
