This paper addresses rate-distortion optimal mode selection, based on estimates of the instantaneous coding distortion, for multi-mode source coders. We propose a two stage estimation framework, including a property extraction, and a Gaussian mixture model based distortion estimation. We also suggest accompanying measures for evaluating the goodness of a given property vector. The proposed framework is evaluated for a set of properties in a CELP coding framework. The results suggest that the proposed framework is capable of doing rate distortion optimal mode selection in multi-mode source coders.
