wasalam bro. ahsan,

The best way is to discuss with your sv as he/she should agree on the subject of research. cv is a field that includes methods for acquiring, processing, analyzing, and understanding images and, in general, high-dimensional data from the real world in order to produce numerical or symbolic information.

The classical problem in computer vision, image processing, and machine vision is that of determining whether or not the image data contains some specific object, feature, or activity. This task can normally be solved robustly and without effort by a human, but is still not satisfactorily solved in computer vision for the general case – arbitrary objects in arbitrary situations. The existing methods for dealing with this problem can at best solve it only for specific objects, such as simple geometric objects (e.g., polyhedra), human faces, printed or hand-written characters, or vehicles, and in specific situations, typically described in terms of well-defined illumination, background, and pose of the object relative to the camera.

As a start try to review/read journal papers ICCV,ECCV,ACCV, IAPR,PAMI, it can give you general idea of latest cv research and which concern you most. You can also participate in any top conference to get idea .kindly refer to for current conferences schedule . http://iris.usc.edu/information/Iris-Conferences.html

Thank you Brother Mohd Norzali...

actually i have discussed it with my supervisor, he said to me that first decide domain in which i want to pursue research and read some research papers on it and try to find some scope of contribution that you can make.

And here is i am a bit confuse.

That's why asking for suggestions.

Thanks for kind opinion dear brother.
