... 4, is used for classification in our implementation. Therefore, 8 bits are needed for ADRC coding, since 1 bit can be saved by bitinversion [15]. For the activity measure, we use 2 bits for local ... LMS-optimized coefficients for each class are then stored in a lookup table (LUT) for future use. Figure 3 shows the fil- tering procedure of resolution upconversion for compressed mate...
