查询词典 market segmentation

In the video segmentation method based on DEMD, the intrinsic mode function with the lowest frequency is discarded and a simple and effective motion compensation method is adopted. As a result, the video segmentation method is no longer sensitive to abrupt change of luminance, object motion in shots, motion and zoom in/out of cameras, so that the precision of detecting shot boundaries is improved.

基于DEMD的视频分割方法除去视频帧中反映图像内光照分布与能量的最低频率固有模态函数(intrinsic mode function，IMF)分量，并选择一种简单有效的运动补偿方法，解决了传统基于直方图方法对光照突变、镜头内物体运动和镜头运动及拉伸的敏感问题，减少了镜头边界识别的误检率，在保证召回率不受影响的前提下提高了视频分割的精确度。

By defining a discriminability function and utilizing some images with synthetic defects, a parameter selection method is proposed to adapt to various fabric types when the Gabor filter bank is applied in defect segmentation. It is argued that only the real part of Gabor filter works during segmentation; the radial orientation can be limited to horizontal and vertical direction; the radial frequency and the length of the FIR filter should depend on the basic frequency of the fabric texture.
