چکیده

In this paper, we describe our method used to achieve our results which was submitted to the Recognition Task of the challenge. As for video features, we combined our proposed feature [1] and the dense trajectories based feature presented in [2]. We employed Fisher Vector encoding to represent videos using these features and trained multiclass linear SVMs to perform action recognition. We conducted experiments on UCF-101 dataset following the suggested competition track evaluation setup and obtained precision rate as 66.5%.

A Dense SURF and Triangulation Based Spatio-temporal Feature for Action Recognition

In this paper, we propose a novel method of extracting spatio-temporal features from videos. Given a video, we extract its features according to every set of N frames. The value of N is small enough to guarantee the temporal denseness of our features. For each frame set, we first extract dense SURF keypoints from its first frame. We then select points with the most likely dominant and reliable ...

Comprehensive Analysis of Dense Point Cloud Filtering Algorithm for Eliminating Non-Ground Features

Point cloud and LiDAR Filtering is removing non-ground features from digital surface model (DSM) and reaching the bare earth and DTM extraction. Various methods have been proposed by different researchers to distinguish between ground and non- ground in points cloud and LiDAR data. Most fully automated methods have a common disadvantage, and they are only effective for a particular type of surf...

Application of Combined Local Object Based Features and Cluster Fusion for the Behaviors Recognition and Detection of Abnormal Behaviors

In this paper, we propose a novel framework for behaviors recognition and detection of certain types of abnormal behaviors, capable of achieving high detection rates on a variety of real-life scenes. The new proposed approach here is a combination of the location based methods and the object based ones. First, a novel approach is formulated to use optical flow and binary motion video as the loc...

3D Classification of Urban Features Based on Integration of Structural and Spectral Information from UAV Imagery

Three-dimensional classification of urban features is one of the important tools for urban management and the basis of many analyzes in photogrammetry and remote sensing. Therefore, it is applied in many applications such as planning, urban management and disaster management. In this study, dense point clouds extracted from dense image matching is applied for classification in urban areas. Appl...

Probabilistic Semi-Dense Mapping from Highly Accurate Feature-Based Monocular SLAM

In the last years several direct (i.e. featureless) monocular SLAM approaches have appeared showing impressive semi-dense or dense scene reconstructions. These works have questioned the need of features, in which consolidated SLAM techniques of the last decade were based. In this paper we present a novel feature-based monocular SLAM system that is more robust, gives more accurate camera poses, ...
