| titleOfInvention | Efficient Fixed-Point Approximation of Forward and Inverse Discrete Cosine Transforms |
| abstract | Techniques for copying the operation of inverse discrete cosine transform using fixed point arithmetic are disclosed. According to these techniques, a matrix of scaled coefficients is generated by multiplying the coefficients of the matrix of encoded coefficients by the scale factor. Next, a matrix of biased coefficients is generated by adding the center point bias value to the DC coefficients of the matrix of scaled coefficients. Fixed-point arithmetic is then used to apply the transform to the matrix of biased coefficients. The values of the resulting matrix are then right-shifted to yield a matrix of pixel component values. The matrix of pixel component values is then combined to produce a matrix of pixels. The matrix of pixels generated by this technique is very similar to the matrix of pixels decompressed using the ideal inverse discrete cosine transform ("IDCT"). |
