[0033] In order to better illustrate the purpose, concrete steps and characteristics of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings:
[0034] refer to figure 1 , a kind of target scale self-adaptive tracking method based on the space-time model proposed by the present invention mainly includes the following steps:
[0035] Step 1. Read in the first frame image Image 1 , manually specify the tracking target rectangle position Ζ;
[0036] Step 2. Based on the context space Ω c , initialize the space-time model make
[0037]
[0038] Step 3. Calculate the target area Z 1 Histogram of directional gradient features f HOG_Z , let m=Z ,f HOG_Z >, M=M∪m, initialize the multi-scale historical target template library M;
[0039] Step 4. Read in the next frame Image t+1 (t≥1);
[0040]
[0041]
[0042] Step 7. Use the target center point estimated in step 6 As the center, e...
