  • Edge preserving noise reduction algorithm using inverse exponential function optimization
    Patent number: 11521300
    Abstract: An apparatus includes a memory and a processing circuit. The memory may be configured to store image data of an image. The processor circuit may be configured to (a) copy the image data of the image from the memory to a first memory buffer of the processor circuit, (b) calculate first vector values for each pixel location in the image using the image data stored in the first memory buffer, (c) calculate second vector values for each pixel location in the image using the image data stored in the first memory buffer and the first vector values, (d) transform the image data stored in the first memory buffer by adding the second vector values to corresponding image data, (e) storing the transformed image data to the memory, and (f) repeating steps (a) through (e) until the image data of the image has been transformed.
