Abstract

An efficient image downconversion algorithm in the compressed domain for mixed field/frame-mode macroblocks is proposed. A 16 × 16 field/frame-mode macroblock is converted into an 8 × 8 reduced block in the discrete cosine transform (DCT) domain using a modified inverse DCT (IDCT) kernel. Experimental results show that the proposed algorithm provides the downconverted image quality similar to an existing method with significantly lower computational cost.
