boofcv.alg.transform.ii.SparseIntegralGradientKernel<T>

All Implemented Interfaces:: SparseImageGradient<T,GradientValue_F64>, SparseImageOperator<T>

public class SparseIntegralGradientKernel<T extends ImageGray<T>> extends Object implements SparseImageGradient<T,GradientValue_F64>

Computes the gradient from an integral image. Does not check for border conditions.

Constructor Details
- SparseIntegralGradientKernel
  
  public SparseIntegralGradientKernel(IntegralKernel kernelX, IntegralKernel kernelY)
Method Details
- isInBounds
  
  public boolean isInBounds(int x, int y)
  
  Description copied from interface: SparseImageOperator
  
  Checks to see if the entire sample region is contained inside the image or not. Depending on the implementation it might be able to handle out of bounds pixels or not.
  
  Specified by:
  
  isInBounds in interface SparseImageOperator<T extends ImageGray<T>>
- setImage
  
  public void setImage(T integralImage)
  
  Description copied from interface: SparseImageOperator
  
  Specifies the image being processed.
  
  Specified by:
  
  setImage in interface SparseImageOperator<T extends ImageGray<T>>
  
  Parameters:
  
  integralImage - Image being processed
- compute
  
  public GradientValue_F64 compute(int x, int y)
  
  Description copied from interface: SparseImageGradient
  
  Computes the gradient at the specified point.
  
  Specified by:
  
  compute in interface SparseImageGradient<T extends ImageGray<T>,GradientValue_F64>
  
  Parameters:
  
  x - x-axis pixel coordinate
  
  y - y-axis pixel coordinate
  
  Returns:
  
  Gradient at that point.
- getGradientType
  
  public Class<GradientValue_F64> getGradientType()
  
  Specified by:
  
  getGradientType in interface SparseImageGradient<T extends ImageGray<T>,GradientValue_F64>
