Improvement of natural image search engines results by emotional filtering

open access: yesEAI Endorsed Transactions on Creative Technologies, 2016
With the Internet 2.0 era, managing user emotions is a problem that more and more actors are interested in. Historically, the first notions of emotion sharing were expressed and defined with emoticons. They allowed users to show their emotional status to

Change Blindness Is Influenced by Both Contrast Energy and Subjective Importance within Local Regions of the Image

open access: yesFrontiers in Psychology, 2017
Our visual system receives an enormous amount of information, but not all information is retained. This is exemplified by the fact that subjects fail to detect large changes in a visual scene, i.e., change-blindness.

Contrast-Independent Biologically Inspired Motion Detection

open access: yesSensors, 2011
Optic flow, i.e., retinal image movement resulting from ego-motion, is a crucial source of information used for obstacle avoidance and course control in flying insects.

Repetition blindness for natural images of objects with viewpoint changes

open access: yesFrontiers in Psychology, 2013
When stimuli are repeated in a rapid serial visual presentation (RSVP), observers sometimes fail to report the second occurrence of a target. This phenomenon is referred to as repetition blindness (RB).

Distinguishing Computer-Generated Graphics from Natural Images Based on Sensor Pattern Noise and Deep Learning

open access: yesSensors, 2018
Computer-generated graphics (CGs) are images generated by computer software. The rapid development of computer graphics technologies has made it easier to generate photorealistic computer graphics, and these graphics are quite difficult to distinguish ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Statistics of gradient directions in natural images. [PDF]

open access: yes, 2007
Interest in finding statistical regularities in natural images has been growing since the advent of information theory and the advancement of the efficient coding hypothesis that the human visual system is optimised to encode natural visual stimuli.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Texture MTF from images of natural scenes [PDF]

open access: yes, 2017
The implementation of automatic, adaptive filters in consumer imaging devices represents challenges to sharpness and resolution evaluation. The widely used e-SFR and other methods based on sine-waves and line targets are not necessarily representative of

Detecting dense text in natural images

open access: yesIET Computer Vision, 2020
Most existing text detection methods are mainly motivated by deep learning‐based object detection approaches, which may result in serious overlapping between detected text lines, especially in dense text scenarios.
