Existing vertex-based shape coding algorithms use a number of different distortion measurement techniques including the shortest absolute distance (SAD), distortion band (DB) or tolerance band (TB), accurate distortion measurement technique for shape coding (ADMSC) and distortion measurement based on chord-length-parameterisation (DMCLP). Among these techniques DMCLP is computationally the fastest. It however, is a relaxed measurement technique and does not fully utilise the admissible distortion within the rate-distortion optimisation. This paper presents a novel distortion measurement technique based on arc-length-parameterisation (DMALP) within the vertex-based shape coding framework. Experimental results vindicate its superior performance over the existing geometric distortion measurement techniques.
