Examples of KernelJAI

com.lightcrafts.mediax.jai.KernelJAI

A kernel representing a matrix with a key position, used by operators such as Convolve .

A KernelJAI is characterized by its width, height, and origin, or key element. The key element is the element which is placed over the current source pixel to perform convolution or error diffusion.

A kernel K is separable it the outer product of two one-dimensional vectors. It can speed up computation. One can construct a kernel from two one-dimensional vectors. <>The symmetry can be useful (such as computation speedup). Currently the protected instance variables isHorizonallySymmetric and isVerticallySymmetric are set to false. @see com.lightcrafts.mediax.jai.operator.ConvolveDescriptor @see com.lightcrafts.mediax.jai.operator.OrderedDitherDescriptor @see com.lightcrafts.mediax.jai.operator.ErrorDiffusionDescriptor
