Class ImageGrid<T>

java.lang.Object

boofcv.struct.ImageGrid<T>

public class ImageGrid<T>
extends Object

Breaks the image up into a grid. For use when processing individual regions of the image at a time. The size of a cell is designed to be approximately the target size, but adjusted to ensure even coverage.

Method Details

initialize

public void initialize(int targetLength,
 int imageWidth,
 int imageHeight)

Initializes the grid based on how many pixels long a cell should be and the image size.

Parameters:

targetLength - Target length of a grid cell in pixels

imageWidth - Image width in pixels

imageHeight - Image height in pixels

getCellAtPixel

public T getCellAtPixel(int pixelX,
 int pixelY)

Returns the cell at the specified pixel. Coordinate must be inside image bounds

get

public T get(int row,
 int col)

Returns the cell element at the specified grid coordinate

processCells

public void processCells(ImageGrid.ProcessCell<T> processor)

Goes through every cell in the grid and passes in data to the processor

processCellsThreads

public void processCellsThreads(ImageGrid.ProcessCell<T> processor)

Same as processCells(boofcv.struct.ImageGrid.ProcessCell<T>) but threaded.
