OTSU Gray-level image segmentation using Otsu s method.
Iseg = OTSU(I,n) computes a segmented image (Iseg) containing n classes
by means of Otsu s n-thresholding method (Otsu N, A Threshold Selection
Method from Gray-Level Histograms, IEEE Trans. Syst. Man Cybern.
9:62-66 1979). Thresholds are computed to maximize a separability
criterion of the resultant classes in gray levels.
OTSU(I) is equivalent to OTSU(I,2). By default, n=2 and the
corresponding Iseg is therefore a binary image. The pixel values for
Iseg are [0 1] if n=2, [0 0.5 1] if n=3, [0 0.333 0.666 1] if n=4, ...
[Iseg,sep] = OTSU(I,n) returns the value (sep) of the separability
criterion within the range [0 1]. Zero is obtained only with images
having less than n gray level, whereas one (optimal value) is obtained
only with n-valued images.

跨數(shù)據(jù)庫平臺:
n 支持 oracle 的OCI
n 支持DB2的CLI,
n 支持ODBC(通過ODBC,可支持SQL SERVER,MySQL等)
Ø 跨OS平臺:
n 標準C++語言,支持 unix/linux/windows
Ø 使用簡單:
n 只有一個頭文件
n 接口簡潔.otl_stream, otl_connect, otl_exception等就可以完成大部分工作
n 相對 ProC等嵌入式開發(fā),代碼能相應減少
Ø 性能:
n 直接訪問數(shù)據(jù)庫API接口,具有API接口的高效率,可靠性
Ø 穩(wěn)定性:
n 開源代碼,唯一的代碼文件otlv4.h,可以了解所有基于數(shù)據(jù)庫API的實現(xiàn)細節(jié)
n 從1996年開始,到今已10余年.
Ø 可讀性及可維護性:
n 標準C++代碼,不需要任何預處理
n 使用流的形式,輸入輸出異常簡潔
n 減少大量代碼,
n 代碼結構更加簡潔
