PostProcessNoiseFilter
unsigned int WINAPI PostProcessNoiseFilter(at_32 * InputImage, at_32 * OutputImage, int
OutputBufferSize, int Baseline, int Mode, float Threshold, int Height, int Width)
Description
This function will apply a filter to the input image and return the processed image in the
output buffer. The filter applied is chosen by the user by setting Mode to a permitted
value.
Parameters
at32* InputImage: The input image data to be processed.
at32* OutputImage: The output buffer to return the processed image.
int OutputBufferSize: The size of the output buffer.
int Baseline: The baseline associated with the image.
int Mode: The mode to use to process the data. Valid options are:
1 – Use Median Filter.
2 – Use Level Above Filter.
3 – Use Interquartile Range Filter.
4 – Use Noise Threshold Filter.
float Threshold: This is the Threshold multiplier for the Median, Interquartile
and Noise Threshold filters. For the Level Above filter this is
Threshold count above the baseline.
int Height: The height of the image.
int Width: The width of the image.
