In this study, a detailed comparative analysis of low bit-depth based motion estimation approaches has been performed on the latest video coding standard HEVC. Thus, actual performance of these approaches has been revealed in a full encoder whereas open loop performance evaluations were carried out in the past mostly. It has also been investigated for the first time in the literature to integrate these approaches with the sparse search based methods on HEVC to further accelerate low bit depth representation based motion estimation approaches. As a result of this work, it has been found that performance degradation will occur if the so-called TZS algorithm used in the HEVC reference software is directly combined with low-bit-depth images.
