Title: 5,3 wavelet filter having three high pair and low pair filter elements with two pairs of cascaded delays

Abstract: A wavelet transform filter is disclosed having a pair of line buffers, three pairs of high and low pass filter pairs, two pairs of cascaded delays, and first and second delays, where the second pair of cascade delays is coupled to the first output and has fourth and fifth delay outputs, and a third high pass filter element having inputs coupled to the first output and the fourth and fifth delay output, where the third high pass filter element generates a fifth output of coefficients in the HH subband. A second delay coupled to the fifth output and has a sixth delay output. A third low pass filter element has inputs coupled to the fifth output, the sixth delay output and the fifth delay output and generates a sixth output corresponding to the coefficients in the HL subband.

Claims

1. A wavelet transform filter comprising:

a first line buffer;

a first high pass filter element having inputs coupled to receive first and second input coefficients and an output of the first line buffer, the high pass filter having a first output;

a second line buffer coupled to receive the first output and having a second line buffer output;

a first low pass filter element having inputs coupled to the first input coefficient, the first output and the second line buffer output, the low pass filter element having a second output;

a first pair of cascaded delays coupled to the second output, the first pair of cascaded delays having first and second delay outputs;

a second high pass filter element having inputs coupled to the second output and the first and second delay outputs, the second high pass filter element to generate a third output, the third output being coefficients in an LH subband;

a first delay coupled to the third output and having a third delay output;

a second low pass filter element having inputs coupled to the third output, the third delay output, and the fourth output, the second low pass filter element to generate a fourth output corresponding to coefficients in the LL subband;

a second pair of cascaded delays coupled to the first output, the second pair of cascaded delays having fourth and fifth delay outputs;

a third high pass filter element having inputs coupled to the first output and the fourth and fifth delay outputs, the third high pass filter element to generate a fifth output, the fifth output being coefficients in an HH subband; and

a second delay coupled to the fifth output and having a sixth delay output;

a third low pass filter element having inputs coupled to the fifth output, the sixth delay output, and the fifth delay output, the third low pass filter element to generate a sixth output corresponding to coefficients in the HL subband.

2. The filter defined in claim 1 wherein the first and second line buffers comprise 1 line buffers.

3. The filter defined in claim 1 further comprising a two line buffer coupled to the fourth output to supply two lines of LL coefficients to a subsequent level of decomposition.

4. The filter defined in claim 1.

5. The filter defined in claim 1 wherein at least one of the first, second or third low pass filter elements comprises hardware that operates according to an equation as follows:

6. The filter defined in claim 5 wherein the first, s
