摘要： One of the challenges in bringing computational imaging to a mass market is that computational imaging is inherently computationally expensive. The computational challenges associated with computational imaging are apparent with the computation of a histogram of gradient descriptors. Oftentimes, generating a histogram of gradient descriptors involves computing gradients of an image, binning the gradients according to their orientation, and, optionally, normalizing the bins using a non-linear function. Because each of these operations is expensive, the histogram of gradient descriptor computations is generally computationally expensive and is difficult to implement in a power efficient manner for mobile applications. The present application discloses a computing device that can provide a low-power, highly capable computing platform for computing a histogram of gradient descriptors.
摘要翻译：将计算成像带入大众市场的挑战之一是，计算成像在本质上是计算上昂贵的。通过计算梯度描述符的直方图，与计算成像相关的计算挑战是显而易见的。通常，生成梯度描述符的直方图包括计算图像的梯度，根据其方向对应梯度，以及可选地使用非线性函数归一化箱。因为这些操作中的每一个都是昂贵的，所以梯度描述符计算的直方图通常在计算上是昂贵的，并且难以以移动应用的功率有效的方式实现。本申请公开了一种计算设备，其可以提供用于计算梯度描述符的直方图的低功率，高功能的计算平台。

摘要： The present application provides a method of corner detection and an image processing system for detecting corners in an image. The preferred implementation is in software using enabling and reusable hardware features in the underlying vector processor architecture. The advantage of this combined software and programmable processor datapath hardware is that the same hardware used for the FAST algorithm can also be readily applied to a variety of other computational tasks, not limited to image processing.
