Method Detail

performProjection

public FImage performProjection(int windowMinC,
                                int windowMaxC,
                                int windowMinR,
                                int windowMaxR,
                                Float backgroundColour)

Perform projection but only request data for pixels within the windowed range provided. Specify the background colour, i.e. the value of pixels with no data post projection.

Overrides:

performProjection in class ProjectionProcessor<Float,FImage>

Parameters:

windowMinC - left X

windowMaxC - right X

windowMinR - top Y

windowMaxR - bottom Y

backgroundColour - background colour of pixels with no data

Returns:

projected image within the window

performBlendedProjection

public FImage performBlendedProjection(int windowMinC,
                                       int windowMaxC,
                                       int windowMinR,
                                       int windowMaxR,
                                       Float backgroundColour)

Perform blended projection but only request data for pixels within the windowed range provided. Specify the background colour, i.e. the value of pixels with no data post projection. This blends any existing pixels to newly added pixels

Overrides:

performBlendedProjection in class ProjectionProcessor<Float,FImage>

Parameters:

windowMinC - left X

windowMaxC - right X

windowMinR - top Y

windowMaxR - bottom Y

backgroundColour - background colour of pixels with no data

Returns:

projected image within the window
