The proposed method first calculates the optimal neighborhood size of each point to derive the geometric features associated with it, and then classifies the point clouds according to geometric features using support vector machines (SVMs). Second, a set of rules are defined to segment the ...
A method for performing content-based temporal segmentation of video sequences, the method comprises the steps of transmitting the video sequence to a processor, identifying within the video sequence a plurality of type-specific individual temporal segments using a plurality of type-specific detectors;...
In this work, a robust method of document images denoising is presented. The simple idea is combining the NLM filter and a Markovian segmentation into regions. The NLM method filtering allows participation of far, but proper pixels in the denoising process. Although the weights of non-similar (...
This paper presents a novel semi-automatic method for lung segmentation in thoracic CT datasets. The fully three-dimensional algorithm is based on a level set representation of an active surface and integrates texture features to improve its robustness. The method’s performance is enhanced by the ...
Moreover, benefit-based segmentation has shown advantages over the item-based segmentation method used in prior research. This study makes a significant contribution to O2O business regarding consumer purchasing behaviors and segmentation methodology....
Medical image segmentation is crucial in diagnosing and treating diseases, but automatic segmentation of complex images is very challenging. Here we present a method, called the crack propagation method (CPM), based on the principles of fracture mechanic
an image segmentation method based on the information fusion of gray information of remote sensing image pixels of every band and texture information of remote sensing image is put forwards from the angle of information fusion,and thus a quadtree-based region split-and-merge algorithm was designed ...
However, the highest accuracy obtained by their method is only 67.95%; thus, segmentation performance needs to be improved. In 2019, Piao Weng et al. [26] proposed a pavement crack segmentation method based on the VGG-U-Net model. It solves the problem of fracture in the crack segmentation...

A robust whistle extraction method on the acoustic signal measured in the coastal habitats of delphinids is still lacking. The whistle extraction process comprises several challenging problems. One is that the amplitude and thickness of the whistle change along its path, which results in a missing ...
