Question

prepare ONE PAGE reflction on Perceiving Objects and Scenes

Answer 1

Perceiving objects and scenes.

There are various objects which can be seen in the external environment. Objects are acted upon and scenes are acted within. Scenes include particluar stages with actors who perform their role and a set of audiences to view them who are considered the objects. Example if one is going to work every morning to an office(scene). The object of this routine is to work of if a person is mailing a letter(object)on the street(scene). There are various scenes which can be perceived in the external environment like watching a TV which includes changing channels rapidly. It includes watching a sports channel, a news channel and an entertainment channel with a summarization of the meaning and implication of all the channels. It is included in the example of perceiving objects and scenes. Mary Porter in 1976 performed a set of experiments of people in which she exposed them to a specific picture and then changed the picture with exposure to several pictures. The people were exposed to a single picture for only 250ms and still they were able to identify the original single picture among a set of pictures. The girl clapping was the picture to be presented. There is persistence of vision which lasts for 250milliseconds even if a person is exposed to this picture for 27ms. After this step is the masking step which includes exposure of few straight lines pciture to people resulting in forgeting the original picture. Observers perceive the objects according to the stimulus and the presence of the objects in the environment. If the exposure time to the objects is increased in the dark pictures also then the small objects in the shown pictures can also be recognised. Aude Olivia and Antonio Torralba used global imaging perspectives. These images are perceived rapidly and have following features like:

• natural
• openess.
• roughness and smoothness of perspectives.
• color
• expansion.
• Experiments were included in the object detection task systems in which the objects were detected were displayed on screens for few seconds. The model consists of target name:
• target name.
• central fixation point.
• scene
• cue of mask.
• The object image is exposed for a certain milliseconds interval of time which has to be recognised by people according to the stimulus in the memory.

There can be position violation which analyzes the scenario and the ability to recognise and perceive objects in reality. There are semantic relations like size, probability and position. The position violation scaling is given during performance of such work with violation of the original rules and service of people recruited to perform that work.
