比较两代运行特征检测算法的嵌入式GPU

Comparing Two Generations of Embedded GPUs Running a Feature Detection Algorithm

Max Danielsson, Håkan Grahn, Thomas Sievert, Jim Rasmusson

摘要:

嵌入式移动平台中的图形处理单元(GPU)正在达到它们可能对计算机视觉应用有用的性能水平。我们比较了两代移动设备的嵌入式GPU在运行最先进的特征检测算法时的情况,即,哈里斯-海森/怪胎。我们比较了索尼Xperia Z3和索尼Xperia XZ移动设备上的架构差异、执行时间、温度和频率。我们的研究结果表明,性能很快就足以进行实时特征检测,GPU没有温度问题,支持大型工作组是很重要的。

英文摘要:

Graphics processing units (GPUs) in embedded mobile platforms are reaching performance levels where they may be useful for computer vision applications. We compare two generations of embedded GPUs for mobile devices when running a state-of-the-art feature detection algorithm, i.e., Harris-Hessian/FREAK. We compare architectural differences, execution time, temperature, and frequency on Sony Xperia Z3 and Sony Xperia XZ mobile devices. Our results indicate that the performance soon is sufficient for real-time feature detection, the GPUs have no temperature problems, and support for large work-groups is important.
