考慮到現有的數字圖像處理都是基于Windows平臺，都或多或少使用了Win32 API函數，不能移植到Linux或者嵌入式系統中。為了使程序可移植，采用標準C語言建立了數字圖像處理的基本框架，如下圖所示：

程序參考了網上一些博客的內容，并進行了改變，建立了符合自己習慣的數據結構。主要實現了bmp格式圖像的打開、保存、創建、圖像顏色空間轉換等功能，暫時還沒有添加具體的處理函數。我想，既然有了程序的框架，添加算法只是編寫一個個函數的問題。

本程序具體實現的功能如下：

* 打開和保存bmp文件，這里使用自定義數據結構Bitmap，相關函數定義如下：
??? bmp.h:
??????? int CreateBitmap(Bitmap* bmp, int width, int height, int bitCount);
??????? void ReleaseBitmap(Bitmap* bmp);
??????? int CheckPath(char *path);
??????? int ReadBitmap(char* path, Bitmap* bmp);
??????? int SaveBitmap(char* path, Bitmap* bmp);

* 圖像格式轉換?
??? basicprocess.h:
??????? int RGB2Gray(Bitmap* src, Bitmap* dst);
??????? int Gray2RGB(Bitmap* src, Bitmap* dst);
??????? int Gray2BW(Bitmap* src, Bitmap* dst, int threshold);
??????? void hsv2rgb(float H, float S, float V, float *R, float *G, float *B);
??????? void rgb2hsv(float R, float G, float B, float *H, float *S, float* V);

程序源碼如下，歡迎大家批評指正。
