一个验证码破解程序. 这个小软件破解验证码的原理,是记忆性破解。读取验证码图片,分成一个个小图片,如果库中有记录,则返回它的验证码字符;如果不存在,则插入新记录。对于没有记忆过的验证码图片,它是识别不出来的。这个破解方法只可用于验证码字符范围固定的验证码。对于不固定范围的,如QQ的注册验证则不能破解。-A code cracking program. This small software, crack code of principles, is memories of crack. Read

机载电子稳像技术研究,很好的一篇博士论文。
本章首先分析了航摄动态图像的特点,并在对机载航摄图像序列进行大量的实
验和理论分析的基础上,提出了适用机载视频图像序列稳定的有效算法,即灰度投影
算法和基于特征点匹配算法。针对灰度投影算法易受图像的背景信息影响的特点,
详细地讨论了如何提高该算法用于机载电子稳像的精度,并通过实验验证了所提方
法的有效性。在长焦距成像系统中,旋转运动对图像序列的稳定有着重要的影响,
机载成像系统在成像过程中,不仅有平移运动,还包含旋转运动,必须考
