Parameterized Appearance Models (PAMs) (e.g. Eigentracking [2], active shape models [6], active appearance models [5, 12], morphable models [3, 11]) are commonly used to model the appearance and shape variation of objects in images. While PAMs have numerous advantages relative to alternative approaches, they have at least two drawbacks. First, they are especially prone to local minima in fittin...

In this article we present a new method for automatic landmark extraction from the contours of biological specimens. Our ultimate goal is to enable automatic identification of biological specimens in photographs and drawings held in a database. We propose to use Active Appearance Models for visual indexing of both photographs and drawings. Automatic landmark extraction will assist us in buildin...

This study compares the impact of an active teaching approach and a traditional (or passive) teaching style on student cognitive outcomes. Across two sections of an introductory business course, one class was taught in an active or “nontraditional” manner, with a variety of active learning exercises. The second class was taught in a passive or “traditional” manner, emphasizing daily lectures. A...

there are several conflicting evidences showing the effect of morphine on learning and memory processes. in the present study the effect of chronic morphine administration on passive avoidance, active avoidance and spatial learning and memory of morphine dependent male rats using passive avoidance shuttle box and morris water maze tasks were investigated, respectively. male rats received morphi...

background: despite a general consensus regarding the impacts of early excision and grafting (ee and g) of burned hand on the reducing of treatment cost and hospital stay, there are some controversial issues about its eff ect on the outcome of hand function.th is study conducted to compare the results of the ee and g and delayed skin grafting in deep hand burns regarding the hand functional out...

the used activated carbon was derived from pine-cone and was used for the removal of acid black 1(ab1) and acid blue 113(ab113) dyes. a batch sorption study was carried out in order to obtain optimum isotherm model. the study showed the best fit of the adsorption isotherm data was obtained using the langmuir model for both dyes. the monolayer maximum saturation capacities of ab1 and ab113 dyes ...
