Method and apparatus for simultaneously convolving multiple digital binary images using a single convolver with a binary mask to determine pixel densities |
摘要 |
A system for simultaneously convolving first and second digital binary images in parallel with a single convolver having a binary mask. A first window is selected from the first digital binary image and a second window is selected from the second digital binary image. A first binary pixel is selected from the first window and a second binary pixel is selected from the second window. The first binary pixel is bit-shifted by concatenating a plurality of trailing zero bits to the first binary pixel. A multi-bit input pixel is formed by combining the bit-shifted first binary pixel and the second binary pixel. A single multi-bit output value is generated by simultaneously applying a plurality of multi-bit input pixels to a single convolver. A first convolution result is formed from only the least significant bits of the output value and a second convolution result is formed from only the most significant bits of the output value, wherein the first and second convolution results respectfully represent the results of sequentially applying a single convolver to the first and second windows. |
