Effective memory management for improving image processing on smartphones

Smartphones have become popular, with people carrying mobile phones at all times and to all places; for example, people use mobile phones to pass time while waiting for a bus. Therefore, if smartphones' features are combined with industrial technology, mobile phones can be used to capture images and the phones' processor can be used to process and treat them, following which the results can be displayed on the phone screen to inform users. Smartphones can be used to quickly analyze and address people's needs, for example, to identify car numbers on license plates and to detect diseases. This article proposes the use of low-cost mobile devices for image processing. In mobile phones, single-core processors and memory performance constraints propose a method to substantially improve the speed of image processing, and verified this method on the smartphone.
