本文对火灾预警中DSP图像处理技术进行了研究。主要内容包括： 1.克服了常规传感器报警的缺点。采用图像型火灾报警系统利用火灾初期的火焰面积逐渐增大、火焰边缘抖动等特征作为火灾判据，消除了周围环境干扰的影响。 2.采用了具有高速度、高精度运算能力的DSP芯片，满足了图像处理中运算量大、实时性强、数据传输速率高等要求。具有功耗低、实时性强的优点。 3.采用基于模糊逻辑的图像识别技术，使系统通过模糊智能算法，把两个火灾判据―“面积增量”和“尖角变化量”有效的结合起来，进行判断。进一步提高了火灾探测的准确性，降低了误报率。 -err

We present a real-time model-based vision approach for detecting and tracking vehicles from a moving platform. It was developed in the context of the CMU Navlab project and is intended to provide the Navlabs with situational awareness in mixed trac. Tracking is done by combining a simple image processing technique with a 3D extended Kalman lter and a measurement equation that projects from the 3D model to image space. No ground plane assumption is made. The resulting system runs at frame rate or higher, and produces excellent estimates of road curvature, distance to and relative speed of a tracked vehicle. We have complemented the tracker with a novel machine learning based algorithm for car detection, the CANSS algorithm, which serves to initialize tracking
