Perceptual image retrieval using eye movements

Perceptual Image Retrieval Using Eye Movements

This paper explores the feasibility of using an eye tracker as an image retrieval interface. A database of image similarity values between 1000 Corel images is used in the study. Results from participants performing image search tasks show that eye tracking data can be used to reach target images in fewer steps than by random selection. The effects of the intrinsic difficulty of finding images ...

Eye tracking : a perceptual interface for content based image retrieval

Image authentication using LBP-based perceptual image hashing

Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of Local Binary Pattern features. In this paper, we investigate the use of local binary patterns for percep...

Perceptual learning modifies untrained pursuit eye movements.

Perceptual learning improves detection and discrimination of relevant visual information in mature humans, revealing sensory plasticity. Whether visual perceptual learning affects motor responses is unknown. Here we implemented a protocol that enabled us to address this question. We tested a perceptual response (motion direction estimation, in which observers overestimate motion direction away ...

A. Eye movements and perceptual bistability

Involuntary eye movements could modulate neural activity and/or perceptual dynamics. If residual eye-movements around the fixation point were not evenly distributed during bound and unbound percepts, they may have altered neural activities differentially during the two percepts. Involuntary smooth pursuit of the diamond during bound percepts would overall have reduced the retinal slip and conse...
