Image Processing Inversion The input image pixel value is inverted and the result is copied to the corresponding output image pixel. Transform Operations Transform operations convert and output a frequency description of the input image. The available operations are a Fast Fourier Transform (FFT) and a Discrete Cosine Transform (DCT). These transforms can be output as 1D Linear, 2D Linear, 2D Logarithmic or His- togram. Logical Operations There are two logical operation modes. In the first, the operation is applied to every pixel of an input image and the corresponding pixel in the Operand image. The result is written in the output image.
In the second mode, the operand is a constant, and it is used on every pixel of the input image and the result is written in the output image. No scaling or clipping is sup- ported for logical operations. AND The logical AND operation is applied using the operand value (constant or Operand image pixel) and the corresponding pixel in the input image. The result is written to the output image. NAND The logical NAND operation is applied using the operand value (constant or Operand image pixel) and the corresponding pixel in the input image. The result is written to the output image.
NOR The logical NOR operation is applied using the operand value (constant or Operand image pixel) and the corresponding pixel in the input image. The result is written to the output image. OR The logical Or operation is applied using the Operand value (constant or Operand image pixel) and the corresponding pixel in the input image. The result is written to the output image. XOR The logical XOR operation is applied using the Operand value (constant or Operand image pixel) and the corresponding pixel in the input image. The result is written to the output image.
