... In the second section, we focus on object search, its concepts and some examples of real-world. We then give the challenges to the research community in the field and some conclusions. 1.1 ... the position list of ZOOM constraint consists of 29, 40, 90 while the position list of NAME constraint includes 25, 30. It is heuristic that the result list should be a combination of 25 and ... merge two position lists into result list by constraint “window -5 5”. In the step S2, after getting position lists of constraints, we have to decide which combination of positions from them...
