Motion Characteristics Based Video Salient Region Extraction Method
Yin Zhou · 2015
The human eyes only observe the salient region of the video.Thus a motion characteristics based salient region extraction method was proposed.Spatial saliency map is extracted by analyzing the log spectrum of each frame in the frequency domain.Temporal saliency map is obtained by global motion estimation and block matching.According to the human visual characteristics and the subjective perception of different motion characteristics,the region of saliency is fused dynamically by spatial and temporal saliency map.The experiment was analyzed from both subjective and objective indicators.Visual observation and quantitative indicators show that the proposed method can reflect the human visual attention area more accurately than other classical extraction methods.
