Abstract: A method for estimating a number of objects is to be implemented by a processing module, and is utilized to estimate a number of a plurality of objects having elongated shapes based on an image of the objects that contains substantially-circular end faces of the objects. The method includes steps of generating a characteristic image based on the image of the objects, the characteristic image containing a plurality of characteristic patterns which are associated with the end faces of the objects, calculating a number of the characteristic patterns based on the characteristic image, and obtaining an estimated number of the objects based on at least the number of the characteristic patterns thus calculated.
Abstract translation: 用于估计多个对象的方法将由处理模块实现，并且用于基于包含对象的基本上圆形端面的对象的图像来估计具有细长形状的多个对象的数量。 该方法包括以下步骤：基于对象的图像生成特征图像，特征图像包含与对象的端面相关联的多个特征图案，基于特征图像计算特征图案的数量; 并且至少基于如此计算的特征图案的数量来获得估计的对象数量。

Abstract: An image-based vehicle classification system includes a camera and an image server connected to the camera. The camera captures images of a road to result in an image stream. The image server includes a processor for receiving the image stream from the camera. For each of the images of the image stream, the processor performs image segmentation, a thinning process, an erosion process and a dilation process, and classifies, by a neural network classifier, a vehicle image part contained in the image into one of a large-size car class, a passenger car class and a motorcycle class when it is determined that the vehicle image is crossing an imaginary line set in advance in the image for counting vehicles.
