Web17 de dez. de 2024 · Unfortunately the forward backwards consistency check is not available in the opencv implementation of the DIS Optical Flow. The problem lies in the inaccuracy of the flow result, and the FW/BW consistency check could improve results e.g. by setting the flow vector entries to NAN for pixels where the FW/BW consistency check … Web7 de dez. de 2024 · 3.Dis光流结果. 说明:将光流场转换到HSV空间中显示,光流的数值用不同颜色来区分,色斑颜色深浅代表运动速率,白色代表物体无运动。 图像说明:左侧彩 …

However, since in particular the DIS flow computes very blurry … Web29 de jul. de 2024 · If you define "flow" as an Image, you will lose information because DISOpticalFlow should return a float matrix. Then convert it to an image by mapping the magnitude and the orientation of the flow to the color space. Any optical flow field is a continuous (i.e. float or double) 2 channel (X and Y pixel motion) map. birds insurance agency
