We address the problem of tracking moving objects through a video sequence using deformable regions. So far, numerous tracking approaches based on region deformation have been proposed and the chosen region-based features are mostly special visual information such as mean-color and texture. This kind of information may be misleading in some dense visual clutter. In this paper, we present a temporal statistical tracking algorithm that extracts the region-based features via adaptive background...

We address the problem of tracking moving objects through a video sequence using deformable regions. So far, numerous tracking approaches based on region deformation have been proposed and the chosen region-based features are mostly special visual information such as mean-color and texture. This kind of information may be misleading in some dense visual clutter. In this paper, we present a temporal statistical tracking algorithm that extracts the region-based features via adaptive background mixture model. Our contribution is to define a new tracking criterion combining geometrical and motional features of the region. The resultant algorithm is expressed in the form of a level set partial differential equation. We also analyzed the adaptive ness of our algorithm. To further improve the computational efficiency, we introduce the narrowband method into our tracking scheme. Finally, highly promising experimental results are provided to illustrate the efficiency and accuracy of our method.

The microstructural evolution and micro-hardness change in a low-carbon vanadium steel ((0.058)%C-0.92%Mn-0.51%V) during isothermal holding after austenite region deformation were investigated with thermo-mechanical test, and the precipitation of V(C,N) was studied through TEM. The experimental results show that the single-phase ferrite matrix microstructure could be obtained by isothermal holding at 650 ℃, 700 ℃ and 750 ℃ after austenite region deformation while the pearlite could be eliminated. During the isothermal holding process, the ferrite nucleated primarily along the anstenite grain boundaries, and then within the austenite grains. Two precipitation modes of V(C,N) were observed in the tested steel: inter-phase precipitation and random precipitation. The inter-phase precipitation of V(C,N) can eliminate the enrichment of carbon in austenite, which is the pre-requisite for the formation of single phase ferrite.

通过热模拟试验,研究了0.058%C-0.92%Mn-0.51%V钢在变形后等温过程中的组织变化规律及显微硬度变化规律,并用透射电镜研究了V(C,N)的沉淀析出规律。结果表明,变形后在650、700、750℃等温100s时可获得单相铁素体组织,从而基本消除珠光体组织。等温转变过程中,铁素体先是主要沿奥氏体晶界形核,随后逐渐变为晶内形核。V(C,N)的沉淀析出存在两种形式:相间析出和随机析出。V(C,N)的相间析出消除了C元素在奥氏体中的富集,是获得单相铁素体组织的重要条件。
