Electronic device and method for operating a presentation application file

An electronic device in communication with a camera module and a projector, the electronic device comprising:

• a storage device;
• at least one processor;
• and
• one or more programs stored in the storage device and being executable by the at least one processor, the one or more programs comprising:
• a processing module operable to acquire a first image of each of a plurality of designated objects using the camera module, and process the first image to acquire a histogram of each of the plurality of designated objects;
• a definition module operable to define an operation corresponding to each of the plurality of designated objects;
• the processing module further operable to acquire a second image from the camera module, process the second image to recognize an object in the second image, and acquire a histogram of the recognized object using log-polar coordinates;
• a calculation module operable to determine a matched designated object by comparing the histogram of the recognized object with the histograms of the designated objects;
• and
• an execution module operable to execute the operation corresponding to the matched designated object to operate a presentation application file projected by the projector, in response to determining that the histogram of the recognized object matches a histogram of a designated object.

A storage medium storing a set of instructions, the set of instructions capable of being executed by a processor to perform a method for operating a presentation application file using an electronic device, the electronic device in communication with a camera module and a projector, the method comprising:

• acquiring a first image of each of a plurality of designated objects using the camera module;
• processing the first image to acquire a histogram of each of the plurality of designated objects;
• defining an operation corresponding to each of the plurality of designated objects;
• acquiring a second image from the camera module, and processing the second image to recognize an object in the second image;
• acquiring a histogram of the recognized object using log-polar coordinates;
• determining a matched designated object by comparing the histogram of the recognized object with the histograms of the designated objects;
• and
• executing an operation corresponding to the matched designated object to operate a presentation application file projected by the projector.
