Abstract
An image encoding/decoding system (10) includes an encoder section (12) and a decoder section (14). The encoder section (12) includes an image detector (15), a transform processor (16), a quantizer (18), a zig-zag process memory (20), and a run/variable length encoder (22). The decoder section includes a variable/run length decoder (24), a dequantizer (26), a zig-zag deprocess memory (28), and an inverse transform processor (30). The inverse transform processor (30) within the decoder section (14) uses basis functions (58) based on a discrete articulated trapezoid transform for ease of realizability in decoding image data. The discrete articulated trapezoid transform may also be used by the transform processor (16) within the encoder section (12) for the encoding of detected images.
