The rapid and detailed recognition of human action from point-light displays is a remarkable ability and very robust against masking by motion signals. However, recognition of biological motion is strongly impaired when the typical point lights are replaced by pictures of complex objects. In a reaction time task and a detection in noise task, we asked subjects to decide if the walking direction...
In image sensing and processing, ambiguities arise when only one source of information is used. Thus, 3D object recognition and localization is a difficult task when using intensity image as single input. This paper presents a machine vision system that uses a Radio Frequency (RF) Tag device to identify objects prior to locating them visually. The tag system consists of a tag reader that can in...
The effect of a sulbutiamine chronic treatment on memory was studied in rats with a spatial delayed-non-match-to-sample (DNMTS) task in a radial maze and a two trial object recognition task. After completion of training in the DNMTS task, animals were subjected for 9 weeks to daily injections of either saline or sulbutiamine (12.5 or 25 mg/kg). Sulbutiamine did not modify memory in the DNMTS ta...
One of the routine memory abilities impaired in amnesic patients with temporal-lobe damage is object-recognition memory--the ability to discriminate the familiarity of previously encountered objects. Reproducing this impairment has played a central role in animal models of amnesia during the past two decades, and until recent years most of the emphasis was on describing how hippocampal damage c...
View based representations have become very popular for recognition tasks. In this contribution, we argue that the potential of the approach is not yet fully tapped: Tasks need not to be “homogeneous”, i.e. there is no need to restrict a system e.g. to either “object classification” or “gesture recognition”. Instead, qualitatively different problems like gesture recognition and scene evaluation...
Neural mechanisms in the temporal lobe are essential for recognition memory. Evidence from human functional imaging and neuropsychology, and monkey neurophysiology and neuropsychology also suggests a role for prefrontal cortex in recognition memory. To examine the interaction of these cortical regions in support of recognition memory we tested rhesus monkeys with prefrontal-inferotemporal (PFC-...
3-D object recognition involves using image-computable features to identify 3-D object. A single view of a 3-D object may not contain sufficient features to recognize it unambiguously. One needs to plan different views around the given object in order to recognize it. Such a task involves an active sensor – one whose parameters (external and/or internal) can be changed in a purposive manner. In...
Introduction: Human and animal models have demonstrated that seizure during pregnancy can cause cognitive and motor impairments in the offspring. However, the mechanisms of this effect need to be elucidated. The purpose of this study was to investigate the effect of seizure during pregnancy on cognitive and motor performances of the adult male offspring with an emphasis on the hypothalamic–pitu...
We describe the object retrieval task of ImageCLEF 2007, give an overview of the methods of the participating groups, and present and discuss the results. The task was based on the widely used PASCAL object recognition data to train object recognition methods and on the IAPR TC-12 benchmark dataset from which images of objects of the ten different classes bicycles, buses, cars, motorbikes, cats...
