Although a high proportion of the motion selective cells in primate motion area, MT, are disparity-selective, there is no convincing evidence for cells in this area specific to stereomotion-in-depth and the neural basis of stereomotion processing remains obscure.
SKIP mode roughly reflects the tendency of motion in a scene, but it can be selected in a fast motion area and not selected in a slow motion area.
If the detected area is in the range of motion area for the hand or foot, the detected area is considered as a hand or foot; otherwise, it is considered as a hand-or-foot candidate area.
In these motion areas, D V has a large value generally because of the feathering artifacts.
However, temporal prediction exhibits poor performance in fast motion areas, because the correlation between the previous picture and the current picture decreases and its rate-distortion cost increases due to large motion vectors.
If the motion activity is less than the threshold, disparity estimation is skipped, because the macroblock is located in a motionless or slow motion area.
The second pathway, named the retino-geniculo-extrastriate (RGES) pathway, connects the retina through the lateral geniculate nucleus to the extrastriate ipsilateral visual cortex, namely the motion area V5/MT in the medial temporal lobe.
Hui Geng was the recipient of a postdoc stipend within the Tissues in Motion program area of Lund University.
In a subsequent study, Martinez-Trujillo and Treue (2002) showed that neurons in motion sensitive area MT behave similarly: They also shift their contrast response function when the stimulus in their RF is attended, in support of what is now called the "contrast gain model" of attention.
Since intra mode is usually selected in very fast motion areas or new object areas, the motion activity is defined as infinite in intra mode.
