Mobile devices are rising to become more powerful and common today with many smart phones now capable to act as small mobile computers, which lead to the rise of various mobile applications. Image processing is another growing field in computing due to the general improvement in computer capability to allow more complicated mathematical computations to be done in a faster speed. This paper sets to experiment the feasibility to apply image processing algorithms on the smart phones running on Android platform for their time performance on five commonly used basic image processing algorithms, i.e. grayscale, Sobel edge detection, averaging filter,...
