public class NppiColorTwistBatchCXR
extends Pointer

\name ColorTwistBatch Perform color twist pixel batch processing. Color twist consists of applying the following formula to each image pixel using coefficients from one or more user supplied color twist device memory matrix arrays as follows where dst[x] and src[x] represent destination pixel and source pixel channel or plane x. The full sized coefficient matrix should be sent for all pixel channel sizes, the function will process the appropriate coefficients and channels for the corresponding pixel size. ColorTwistBatch generally takes the same parameter list as ColorTwist except that there is a list of N instances of those parameters (N > 1) and that list is passed in device memory; The matrix pointers referenced for each image in the batch also need to point to device memory matrix values. A convenient data structure is provided that allows for easy initialization of the parameter lists. The only restriction on these functions is that there is one single ROI which is applied respectively to each image in the batch. The primary purpose of this function is to provide improved performance for batches of smaller images as long as GPU resources are available. Therefore it is recommended that the function not be used for very large images as there may not be resources available for processing several large images simultaneously.

      dst[0] = aTwist[0][0] * src[0] + aTwist[0][1] * src[1] + aTwist[0][2] * src[2] + aTwist[0][3]
      dst[1] = aTwist[1][0] * src[0] + aTwist[1][1] * src[1] + aTwist[1][2] * src[2] + aTwist[1][3]
      dst[2] = aTwist[2][0] * src[0] + aTwist[2][1] * src[1] + aTwist[2][2] * src[2] + aTwist[2][3]
