实时图像处理被认为是一项高处理能力消耗的任务。智能相机通过在相机架构中添加嵌入式处理资源来解决这个问题。这样，早期的低级视觉任务可以在传输到主机系统之前在内部完成，并有助于防止通信瓶颈。本文提出了一种可配置的基于窗口的处理元件，专为在 FPGA 设备上实现而定制。图像过滤、特征检测、跟踪等通常需要基于窗口的操作。在这项工作中，分析了这些应用的一些特殊点，并表明可以提取通用的计算模型。该模型用于构想一个能够执行多种基于窗口的操作的处理元件。提出了可配置的基于窗口的操作器的硬件实现，并且提出并详细介绍了能够托管此类处理元件的智能相机平台。
Image processing in real-time is known as a high processing-power consuming task. Smart cameras deal with this problem by adding embedded processing resources to the camera architecture. This way, early low-level vision tasks can be done internally, before transmission to the host system and helping to prevent from communication bottlenecks. This paper presents a configurable window-based processing element, tailored for implementation on a FPGA device. Window-based operations are often required for image filtering, feature detection, tracking, etc. In this work, some particular points of these applications are analyzed, and it is shown that a general computational model can be extracted. This model is applied to conceive a processing element, able to perform several window-based operations. A hardware implementation of the configurable window-based operator is proposed, and a smart camera platform, able to host such processing element, is presented and detailed.
