- 雜湊法(Hashing)的搜尋與一般的搜尋法(searching)是不一樣的。在雜湊法中，鍵值(key value)或識別字(identifier)在記憶體的位址是經由函數(function)轉換而得的。此種函數，一般稱之為雜湊函數(Hashing function)或鍵值對應位址轉換(key to address transformation)。對於有限的儲存空間，能夠有效使用且在加入或刪除時也能快的完成，利用雜湊法是最適當不過了。因為雜湊表搜尋在沒有碰撞(collision)及溢位(over

cmap
- 这是一个从区位码到Unicode码的变换模块，在汉字处理时经常会用到这种程序，它通过读取一个转换文件，构建一个散列查找表，用于完成从区位码到Unicode码的变换。通过反转码表或者更改码表，该模块还可用于反向变换，或者用于其它需要快速变换的地方。 该模块中包含了足够的源文件，都是以标准C编制的，可以在任何编译环境下进行编译，并提供了调用例子及测试文件。接口定义见cmap.cpp文件。-This is an area code from Unicode code to transfor

Image-Hashing-based-on-Human-Visual-System
- 提出一种基于视觉特性的图像摘要算法，增大人眼敏感的频域系数在计算图像Hash时的权重，使得图像Hash更好地体现视觉特征，并提高鲁棒性。将原始图像的分块DCT系数乘以若干由密钥控制生成的伪随机矩阵，再对计算的结果进行基于分块的Watson人眼视觉特性处理，最后进行量化判决产生固定长度的图像Hash序列。本算法比未采用视觉特性的算法相比，提高了对JPEG压缩和高斯滤波的鲁棒性。图像摘要序列由密钥控制生成，具有安全性。
hash
- Hashing is a technique that allows insertions, deletions and searches of records according to keys in constant average time. In this tutorial, we will construct a hash table and implement its operations.
