Review of Action Recognition and Detection Methods
In computer vision, action recognition refers to the act of classifying an action that is present in a given video and action detection involves locating actions of interest in space and/or time. Videos, which contain photometric information (e.g. RGB, intensity values) in a lattice structure, contain information that can assist in identifying the action that has been imaged. The process of act...
متن کاملRecognition of Arm Movements
This paper describes a method for detection, tracking and recognition of lower arm and hand movements from color video sequences using a linguistic approach driven by motion analysis and clustering techniques. The novelty of our method comes from (i) automatic arm detection, without any manual initialization, foreground or background modeling, (ii) gesture representation at different levels of ...
متن کاملSpace-Variant Descriptor Sampling for Action Recognition Based on Saliency and Eye Movements
Algorithms using “bag of features”-style video representations currently achieve state-of-the-art performance on action recognition tasks, such as the challenging Hollywood2 benchmark [1,2,3]. These algorithms are based on local spatiotemporal descriptors that can be extracted either sparsely (at interest points) or densely (on regular grids), with dense sampling typically leading to the best p...
متن کاملEye Movements During Action Observation
An important element in social interactions is predicting the goals of others, including the goals of others' manual actions. Over a decade ago, Flanagan and Johansson demonstrated that, when observing other people reaching for objects, the observer's gaze arrives at the goal before the action is completed. Moreover, those authors proposed that this behavior was mediated by an embodied process,...
متن کاملAction Representation and Recognition
Recognizing human actions is an important and challenging topic in computer vision, with many important applications including video surveillance, video indexing and understanding of social interaction. From a computational perspective, actions can be defined as four-dimensional patterns, in space and in time. Such patterns can be modeled using several representations which differ from each oth...
