NAME
mlib_ImageHistogram - histogram SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageHistogram(mlib_s32 **histo, const mlib_image *img); DESCRIPTION
The mlib_ImageHistogram() function creates a histogram. The data type of the image can be MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT. PARAMETERS
The function takes the following arguments: histo Pointer to histogram. The format of the histogram is histo[channel][index]. The MLIB_BYTE type entries are indexed from 0 to 255. The MLIB_SHORT type entries are indexed from -32768 to -1, then from 0 to 32767. The MLIB_USHORT type entries are indexed from 0 to 65535. The MLIB_INT type entries are indexed from -2147483648 to -1, then from 0 to 2147483647. img Pointer to source image. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

NAME
mlib_ImageLookUp - table lookup SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageLookUp(mlib_image *dst, const mlib_image *src, const void **table); DESCRIPTION
The mlib_ImageLookUp() function maps the source image to the destination image by using the user-specified lookup table. The source and destination images must have the same width and height. The source image can be a single channel image or can have the same number of channels as the destination image. One of the following equations is used accordingly: dst[x][y][i] = table[i][src[x][y][0]] dst[x][y][i] = table[i][src[x][y][i]] The source and destination images can have different data types. See the following table for available variations of the table lookup func- tion on image types: Type [*] BYTE SHORT USHORT INT FLOAT DOUBLE MLIB_BIT Y MLIB_BYTE Y Y Y Y Y Y MLIB_SHORT Y Y Y Y Y Y MLIB_USHORT Y Y Y Y Y Y MLIB_INT Y Y Y Y Y Y [*] Each row represents a source data type. Each column represents a destination data type. PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. table Pointer to lookup table. The data type of the lookup table is the same as the destination image. The number of entries in the lookup table is determined by the type of the input image. The format of the lookup table is: table[channel][index] The MLIB_BIT type entries are indexed from 0 to 1. The MLIB_BYTE type entries are indexed from 0 to 255. The MLIB_SHORT type entries are indexed from -32768 to -1, then from 0 to 32767. The MLIB_USHORT type entries are indexed from 0 to 65535. The MLIB_INT type entries are indexed from -2147483648 to -1, and then from 0 to 2147483647. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
