Automatic segmentation of colon glands using object-graphs
Gland segmentation is an important step to automate the analysis of biopsies that contain glandular structures. However, this remains a challenging problem as the variation in staining, fixation, and sectioning procedures lead to a considerable amount of artifacts and variances in tissue sections, which may result in huge variances in gland appearances. In this work, we report a new approach fo...
متن کاملVideo Object Segmentation Using Graphs
This paper presents an approach for video object segmentation. The main idea of our approach is to generate a planar, triangulated, and labeled graph that describes the scene, foreground objects and background. With the help of the KLT Tracker, corner points are tracked within a video sequence. Then the movement of the points adaptively generates a planar triangulation. The triangles are labele...
متن کاملAutomatic Video Sequence Segmentation Using Object Tracking
Emerging video standards address content-based function-alities and interactive multimedia. MPEG-4 segments the frames into video object planes (VOP) with each VOP corresponding to one semantically meaningful object. In this paper a new automatic video sequence segmentation algorithm is presented that can extract such VOP's. A binary model for moving objects is automatically derived and tracked...
متن کاملautomatic verification of authentication protocols using genetic programming
implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
15 صفحه اولAutomatic Video Object Segmentation Using Volume Growing and Hierarchical Clustering
We introduce an automatic segmentation framework that blends the advantages of color, texture, shape, and motion based segmentation methods in a computationally feasible way. A spatiotemporal data structure is first constructed for each group of video frames, in which each pixel is assigned a feature vector based on low-level visual information. Then, the smallest homogeneous components, so cal...
