H.264/AVC video coding standard with hierarchical bipredictive picture (HBP) generally outperforms the other prediction structures such as ‘IPPP…’ and ‘IBBP…’ through better exploitation of data correlation using the preceding and succeeding reference frames. However, due to the different coding order of frames, the HBP scheme could not fully exploit the data correlations using multiple reference...
In this paper, we present a mobile healthcare application that applies color quantization technique in analysis of color images taken by a camera phone to automate pH classification of medical tests. Experimental results and comparative study have demonstrated the advantages of this new approach in terms of efficiency, accuracy, and robustness over the solution developed earlier based on edge detectors.
