    • The disclosed segmentation method and system (collectively "system") identifies a region-of-interest within an ambient image captured by a sensor. The ambient image includes the target image (the "segmented image" of the target), as well as the area surrounding the target. The disclosed system purposely "under-segments" the ambient image and the process is typically followed by a subsequent segmentation process to remove the portions of the region-of-interest image that do not represent the segmented image. The system compares the ambient image captured by the sensor with a template ambient image without a target to assist in identifying the region-of-interest. They system performs a watershed heuristic to further remove portions of the ambient image from the region-of-interest. In a safety restraint embodiment of the system, the region-of-interest can be used by the safety restrain application to determine the classification of the vehicle occupant, and motion characteristics relating to the occupant.
    • 公开的分割方法和系统(统称为“系统”)识别由传感器捕获的环境图像内的感兴趣区域。 环境图像包括目标图像(目标的“分割图像”)以及目标周围的区域。 所公开的系统有意地“下划线”环境图像,并且该过程通常后跟随后的分割处理以去除不表示分割图像的感兴趣区域图像的部分。 该系统将传感器捕获的环境图像与模板环境图像进行比较,而无需目标,以帮助识别感兴趣的区域。 他们系统执行分水岭启发式,以进一步从感兴趣的区域去除环境图像的部分。 在系统的安全约束实施例中,安全限制应用可以使用感兴趣区域来确定车辆乘员的分类以及与乘客相关的运动特性。
