Kinect Sensing of Shopping Related Actions

Abstract

Abstract. Surveillance systems in shopping malls or supermarkets are usually used for detecting abnormal behavior. We used the distributed video cameras system to design digital shopping assistants which assess the behavior of customers while shopping, detect when they need assistance, and offer their support in case there is a selling opportunity. In this paper we propose a system for analyzing human behavior patterns related to products interaction, such as browse through a set of products, examine, pick products, try on, interact with the shopping cart, and look for support by waiving one hand. We used the Kinect sensor to detect the silhouettes of people and extracted discriminative features for basic action detection. Next we analyzed different classification methods, statistical and also spatio-temporal ones, which capture relations between frames, features, and basic actions. By employing feature level fusion of appearance and movement information we obtained an accuracy of 80% for the mentioned six basic actions.

“…Consequently, topological detection becomes not less, if not more, valuable for theory and practice than energy detection. The theory of topological detection is formulated in [1][2][3][4][5][6][7][8][9][10][11][12][17][18][19][20][21][22][23][24][25][26][27][28]. It is especially necessary for the purpose of reexamining the former theory and in that way producing new results that are not available to traditional concepts of radiolocation.…”

“…Not results, not specific solutions are the most valuable, bur namely the solution method, the approach to it. The created method is presented in [1][2][3][4][5][6][7][8][9][10][11][12][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34].…”

“…Moreover, the texture also determines lacunarity Λ (Fig. 5), which uses second-order statistics for fractal images [1][2][3][4][5][6][7][8][9][10][11][12][17][18][19][20][21][22][23][24][25][26][27][28]. Lacunarity is small for large dense texture and it is great when the texture is coarse-grained.…”

“…2 and 3) the operation of the working model of fractal nonparametric detector of radar signals (FNDRS) was performed in [2003][2004][2005]. [1][2][3][4][5][6][7][8][9][10][11][12][17][18][19][20][21][22][23][24][25][26][27][28]. In 2005 in the US it was exhibited as part of ISTC project with CCB "Almaz" and IRE RAS and earned a very high opinion of experts [1,2].…”

“…Thus, motion integrals are not conserved in transnuclear interaction: momentum conservation law, angular momentum (spin) conservation law, and, apparently, energy conservation law are violated. As a result, nonradiative, low-energy multinuclear reactions automatically take place in nuclear transmolecule [11][12][13][14][16][17][18][19][20][21][22][23][24][25][26][27].…”
