IMAGEETRACT
- 利用Matlab提取图片中的数据 从事科研或者工程的人员在文档撰写过程中，常需要将文献中的曲线与自己的结果对比，为获取原始数据，一种常用的办法是手动描点，即将原始曲线放大然后打印出来，选取一定数量的点，读出其横纵坐标，然后重绘。对于较为平坦的曲线，这种方法当然可行，但当曲线数量增加，曲线变化复杂，这种方法工作量可想而知。前段时间由于原始数据丢失，仅剩几十幅图片，本人尝试过手动描点，经历几个小时奋战，实在无法继续，索性转向matlab，借助其强大的数据处理能力，编写了两个GUI的小软件ima
slides
- 用双向链表实现了存储数据的功能。使用了两个链表，分别存储编号对应的幻灯片的两个点对应的坐标，以及序号对应的点的坐标。采用蛮力算法，找每个点是否只落在一个幻灯片所在的区域内，如果只有一个则记下该序号，并且删除该幻灯片和序号；如果出现多于一个的情况，立即跳出for循环，进行对下一个序号点的检验工作；如果没有落入任何一个幻灯片，则表明无解，直接输出-1停止。外面使用了一个虚假的while循环，判读条件是现在是否还有幻灯片以及上一次没有进行for循环时的幻灯片数和现在的片数是否相等：如果相等，表明已经不
Plate-recognition-system-source-code
- 本源码是基于MATLAB实现车牌识别并语音播报。 本系统针对家庭小型车蓝底白字车牌进行识别。根据彩色图像的RGB比例定位出近似蓝色的候选区域。但是由于RGB三原色空间中两点间的欧氏距离与颜色距离不成线性比例，在设定蓝色区域的定位范围时不能很好的控制。因此造成的定位出错是最主要的。这样在图片中出现较多的蓝色背景情况下识别率会下降，不能有效提取车牌区域。对此本文提出了自适应调节方案。对分割出来的区域进行识别调整。根据长宽比，蓝白色比对候选区域进行多次定位。最终找到车牌区域。 对字符正确识别之
