The advent of GPUs with programmable shaders on mobile phones has motivated developers to utilize GPU to offload computationally intensive tasks and relive the burden of embedded CPU. In this paper, we present a set of metrics to measure characteristics of a mobile phone GPU with the focus on image processing algorithms. These measures assist users in(More)
This letter proposes a novel warping-based method for the content-driven retargeting of stereoscopic images. Conventional algorithms in single image retargeting generally do not consider the scene depth saliency and disparity consistency when applied independently to left and right images . Therefore, the salient region and stereoscopic correlation of(More)
SUMMARY In this paper, we analyze the key factors underlying the implementation, evaluation, and optimization of image processing and computer vision algorithms on embedded GPU using OpenGL ES 2.0 shader model. First, we present the characteristics of the embedded GPU and its inherent advantage when compared to embedded CPU. Additionally , we propose(More)
This paper proposes an affine projection algorithm (APA) using the inner product between input vectors. The existing APAs have fast convergence rate but large steady-state estimation errors. In order to reduce the estimation errors, the proposed algorithm adjusts the number of the input vectors by grouping of the input vectors. The grouping process uses the(More)
