Saliency Changes Appearance
Numerous studies have suggested that the deployment of attention is linked to saliency. In contrast, very little is known about how salient objects are perceived. To probe the perception of salient elements, observers compared two horizontally aligned stimuli in an array of eight elements. One of them was salient because of its orientation or direction of motion. We observed that the perceived ...
متن کاملCrowding Changes Appearance
Crowding is the breakdown in object recognition that occurs in cluttered visual environments and the fundamental limit on peripheral vision, affecting identification within many visual modalities and across large spatial regions. Though frequently characterized as a disruptive process through which object representations are suppressed or lost altogether, we demonstrate that crowding systematic...
متن کاملSaliency of Interest Points under Scale Changes
Interest point detectors are commonly employed to reduce the amount of data to be processed. The ideal interest point detector would robustly select those features which are most appropriate or salient for the application and data at hand. There is however a tradeoff between the robustness and the discriminance of the selected features. Whereas robustness in terms of repeatability is relatively...
متن کاملAssessing of Fabric Appearance Changes Using Image Processing Techniques
This paper describes the use of image processing to measure lightness changes of fabric appearance. The lightness changes due to dyeing, washing and exposure to light treatments are studied. These properties are measured by using the changes in the intensity levels of the fabrics image and the L* obtained by a spectrophotometer. For each case, analysis of variance (ANOVA) is carded out and the...
متن کاملRelocalization under Substantial Appearance Changes using Hashing
Localization under appearance changes is essential for robots during long-term operation. This paper investigates the problem of place recognition in environments that undergo dramatic visual changes. Our approach builds upon previous work on graph-based image sequence matching and extends it by incorporating a hashing-based image retrieval strategy in case of localization failures or the kidna...
