Increasing task demand by obstructing object recognition increases boundary extension

Pattern Recognition Methods for Object Boundary Detection

Boundary extraction is a data representation problem: image features are segmented and approximated by a parametric curve or a sequence of model points. However, the use of classic Pattern Recognition methods in boundary detection is unusual when compared with more popular approaches, e.g., active contours. This can be partially explained by their inability to separate boundary edges from other...

Task and object learning in visual recognition

Human performance in object recognition changes with practice, even in the absence of feedback to the subject. The nature of the change can reveal important properties of the process of recognition. We report an experiment designed to distinguish between non-specific task learning and object-specific practice effects. The results of the experiment support the notion that learning through modifi...

the effects of spironolactone on morphine withdrawal induced memory loss by the object recognition task method in mice

previous reports showed that elevated levels of glucocorticoids following morphine withdrawal play an important role in memory impairment. in addition, glucocorticoid receptor (gr) inhibitors improved memory perfor-mance in morphine withdrawal mice. since mineralocorticoid receptor (mr) and grs complement each other, the aim of the current study was to evaluate the effects of spironolactone on ...

effects of acute administration of urtica dioica on the novel object-recognition task in mice

conclusions acute administration of u. dioica impairs the object-recognition task if it is used only before the training session. this may be due to its modulation on the acquisition processing of object-recognition. u. dioica has no significant effects on the consolidation or retrieval processing stages of the nor task. these results emphasize the unfavorable effect on cognitive function of pr...
