Perform Pixel-Based Operations on GPU

Perform pixel-based operations on a GPU by using functions that send both the data and the operations to the GPU for processing. This method is most effective for element-wise operations that require two or more data sets.

(Image Processing Toolbox)

Perform Thresholding and Morphological Operations on GPU

Perform image processing operations on a GPU. The example uses filtering to highlight the watery areas in an aerial photograph.
