Sift and Sort: Climbing the Semantic Pyramid
نویسندگان
چکیده
Information processing operations in support of intelligence analysis are of two kinds. They may sift relevant data from a larger body, thus reducing its quantity, or sort that data, thus reducing its entropy. These two classes of operation typically alternate with one another, successively shrinking and organizing the available data to make it more accessible and understandable. We term the resulting construct, the “semantic pyramid.” We sketch the general structure of this construct, and illustrate two adjacent layers of it that we have implemented in the Ant CAFÉ.

Registration of Remote Sensing Images with Steerable Pyramid Transform and Robust SIFT Features
This paper proposes an automatic registration technique based on steerable pyramid transform and robust shift invariant feature transform (SIFT) features, which can deal with the large variations of scale, rotation and illumination of the images. First, the steerable pyramid transform is used to the two input images and the sub-band images along certain orientations are obtained at each layer. ...
متن کاملCombined Descriptors in Spatial Pyramid Domain for Image Classification
Recently spatial pyramid matching (SPM) with scale invariant feature transform (SIFT) descriptor has been successfully used in image classification. Unfortunately, the codebook generation and feature quantization procedures using SIFT feature have the high complexity both in time and space. To address this problem, in this paper, we propose an approach which combines local binary patterns (LBP)...
متن کاملEfficient Construction of SIFT Multi-scale Image Pyramids for Embedded Robot Vision
Multi-scale interest point detectors such as the one used in the SIFT object recognition framework have been of interest for robot vision applications for a long time. However, the computationally intensive algorithms used for the construction of multi-scale image pyramids make real-time operation very difficult to be achieved, especially when a lowpower embedded system is considered as platfor...
متن کاملCritical Analysis of the Moral-Spiritual Teaching of “abandonment of Worldly Belongings” (from Quiddity, its Feasibility and Desirability to the Analysis of Semantic Evolution of the World)
Analysis of quiddity, feasibility and desirability of “abandonment of worldly belongings” as one of the emphatic recommendations in the Islamic teachings and mystical literature is the subject of this article. While criticizing some preconceptions of this issue such as the darkness of the world, this phenomenological study will provide the basis for a correct explanation of the Islamic view of ...

We report on our results in the TRECVID 2011 Multimedia Event Detection (MED) and Semantic Indexing (SIN) tasks. Generally, both of these tasks consist of three main steps: extracting features, training detectors and fusing. In the feature extraction part, we extracted many low-level features, high-level features and text features. We used the Spatial-Pyramid Matching technique to represent the...
