Computation-aware motion estimation algorithm based on QoE control

For the real-time video encoding on mobile devices, a QoE calculation model with two experience dimensions is designed in this paper, so users can select and adjust between video quality and duration. The QoE calculation model is used in the proposed novel one-pass computation-aware motion estimation algorithm in which blocks are divided into four categories. The computation which a frame can use is divided into two parts of the base layer and the gain layer, and then is allocated to four types of blocks respectively, meanwhile early termination detection and adaptive computation allocation strategy are taken in the algorithm. Experimental results show that our algorithm can more accurately to allocate computation and the QoE calculation model has practicality.
