Abstract: A method implemented using a processor based device is disclosed. The method includes receiving a video stream comprising a plurality of image frames having at least one moving object, determining a difference between at least two image frames among the plurality of image frames and generating a difference image comprising a plurality of image blobs corresponding to the at least one moving object. The method further includes generating a plurality of bounding boxes, each bounding box surrounding at least one corresponding image blob among the plurality of image blobs, and determining a subset of bounding boxes among the plurality of bounding boxes, associated with the corresponding moving object, using a fuzzy technique based on a perceptual characterization of the subset of bounding boxes. The method also includes merging the subset of bounding boxes to generate a merged bounding box enclosing the subset of bounding boxes to detect the moving object.

Abstract translation: 公开了一种使用基于处理器的设备实现的方法。 该方法包括接收包括具有至少一个运动对象的多个图像帧的视频流，确定多个图像帧中的至少两个图像帧之间的差异，并生成包括对应于该图像帧的多个图像斑点的差分图像 至少一个移动物体。 该方法还包括生成多个边界框，每个边界框围绕多个图像斑点中的至少一个对应图像斑点，以及使用与相应运动对象相关联的多个边界框中的边界框的子集，使用 基于对包围子集的感知表征的模糊技术。 该方法还包括合并边界框的子集以生成包围边界子集的合并边界框以检测移动对象。
