In this paper, we propose an object recognition method for 2D objects using wavelet descriptors. The descriptors are derived from the continuous wavelet transform using the Mexican hat function as mother wavelet. In contrast to the other known methods we apply an angle function to describe object contours extracted as polygons. The contour extraction is based on the object oriented contour extr...

Appearance-based generic object recognition is a challenging problem because all possible appearances of objects cannot be registered, especially as new objects are produced every day. Function of objects, however, has a comparatively small number of prototypes. Therefore, function-based classification of new objects could be a valuable tool for generic object recognition. Object functions are ...

As the recent developments in humanoid robotics, there is growing interest in object recognition and learning, since they are essential tasks for robots to work in our surrounding environments. Most frameworks for recognition and learning are based only on visual features. It seems that those are insufficient for ’understanding’ of objects, since each object has its own intended use leading to ...

This paper presents a method for estimating the development size and eeort of object oriented software. In an approach analogous to function points, counts of the elements in a static object model are combined to produce a composite measure. Rules are proposed for counting \Object Oriented Function Points" from an object model, and several questions are identiied for empirical research. A key a...

– one of the important applications of robots is in material handling and transport of various shaped objects. in cases where an object cannot be directly grasped by the robot gripper, and must be carried by a hook, it may be subject to undesirable swings during transport. this paper presents an analytical method for minimizing the oscillation of a suspended object during transport. this method...

Object semantics include object function and manipulation knowledge. Function knowledge refers to the goal attainable by using an object (e.g., the function of a key is to open or close a door) while manipulation knowledge refers to gestures one has to execute to use an object appropriately (e.g., a key is held between the thumb and the index, inserted into the door lock and then turned). To da...

abstract background: personality disorders have essential roles in developing and maintaining depressive episodes, though psychotherapies must approach both symptoms and personality problems. this study examined the efficacy of brief object relations psychotherapy on depression severity and perceived quality of life of women suffer from major depressive disorder comorbid with cluster c personal...

over the past years, lake water levels have decreased considerably by various factors and the subsequent emergence of salt plain has brought disastrous consequences that need an essential action. therefore, this study aimed to investigate the effects of drying up and increasing lake water salt and landsat satellite images were used during different time periods in 9 years. to identify the new a...

As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...

This study investigated the association between Iranian university students' perception of their fathers and their object-relation and defense mechanism. Participants were 438 students between 18-22 years from Allameh Tabatabae University, who agreed to fill the Fatherhood Scale out (Dick, 2004), Bell object relation inventory and defense mechanism style, and defense style questionnaire (DSQ-40...
