A Novel Mechanism for Low Bit-Rate Compression
K Reddy · IOSR Journal of Electronics and Communication Engineering · 2013
Sparse sampling techniques have been around in digital photography.In this approach compression follows oversampling.In this paper a uniform down sampling is practically implemented.Moreover it supports adaptive sampling with low-pass and varying pre-filtering.The result of this can be compressed and then sent across to destination without making changes to current image.A decoder is built in MATLAB which decompresses image using the low-pass pre-filtering approach.The proposed approach is known as adaptive down sampling and up conversion which is far better than JPEG 2000.The prototype application is built to evaluate this fact.The proposed system exhibited low-bit rates with higher visual quality.The results revealed that the proposed method can be used in real world applications.
