Abstract
The invention relates to a method for bounding an object in a video sequence F. The method includes obtaining a subset of pixels located in the object to annotate, in each frame of the video sequence. Spatio-temporal slicing is performed on the video sequence F, centered on the obtained subsets of pixels, resulting in a first image Fobtained by an horizontal concatenation of first slices, comprising the obtained subsets of pixels, and resulting in a second image Fobtained by a vertical concatenation of second slices. A trajectory of the obtained subsets of pixels is displayed on both the first Fand second Fimage. A bounding form around the object to annotate is obtained out of four points in each frame of the video sequence, wherein the coordinates of the four points of a frame t are obtained from the coordinates of the points located in the first and second boundary of the first and second image for that frame t.
