ComputeRegionMeanColor

protected ComputeRegionMeanColor(int numBands)

Constructor

Parameters:

numBands - Number of bands in the color image

Method Details

process

public void process(T image,
 GrayS32 pixelToRegion,
 DogArray_I32 regionMemberCount,
 DogArray<float[]> regionColor)

Compute the average color for each region

Parameters:

image - Input image

pixelToRegion - Conversion between pixel to region index

regionMemberCount - List which stores the number of members for each region

regionColor - (Output) Storage for mean color throughout the region. Internal array must be fully declared.

addPixelValue

protected abstract void addPixelValue(int index,
 float[] sum)

Image type specific implementation. Adds the pixel value at the specified pixel to sum

Parameters:

index - Pixel index in the image which is being read

sum - Where the pixel's value is added to
