Infants' perception of lightness changes related to cast shadows. [PDF]

PLoS ONE, 2017
When humans perceive the lightness of an object's surface in shadows there is an implicit assumption that cast shadows dim the surface. In two experiments, we investigated whether 5- to 8-month-old infants make this assumption about shadows. According to

Composition tools for contemporary minimalistic architecture / Kompozicinės priemonės šiuolaikinėje minimalistinėje architektūroje

Journal of Architecture and Urbanism, 2012
• Colour, light, shadows. The chapter deals with the role of these compositional means in the minimal expression. They are considered to be the most important means of the minimal composition and they are compared to the idea and space.

Detecting shadows and low-lying objects in indoor and outdoor scenes using homographies [PDF]

, 2005
Many computer vision applications apply background suppression techniques for the detection and segmentation of moving objects in a scene. While these algorithms tend to work well in controlled conditions they often fail when applied to unconstrained ...

Use of the SAR Shadowing Effect for Deforestation Detection with Sentinel-1 Time Series

Remote Sensing, 2018
To detect deforestation using Earth Observation (EO) data, widely used methods are based on the detection of temporal changes in the EO measurements within the deforested patches. In this paper, we introduce a new indicator of deforestation obtained from

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Insignificant shadow detection for video segmentation

, 2005
To prevent moving cast shadows from being misunderstood as part of moving objects in change detection based video segmentation, this paper proposes a novel approach to the cast shadow detection based on the edge and region information in multiple frames.

Out of the shadows: automatic fish detection from acoustic cameras

, 2022
Efficacious monitoring of fish stocks is critical for efficient management. Multibeam acoustic cameras, that use sound-reflectance to generate moving pictures, provide an important alternative to traditional video-based methods that are inoperable in ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Extension and the Ground in Motion’s Gestalt: Literal and metaphoric

Gestalt Theory
We propose that in pictures both the extended limbs of actors and the ground are involved in gestalts for movement. Limbs extend to suggest more motion literally when a dancer is in air and refer to a canonical pose when on the ground.

The Effect of Negative Samples on the Accuracy of Water Body Extraction Using Deep Learning Networks

Remote Sensing, 2023
Water resources are important strategic resources related to human survival and development. Water body extraction from remote sensing images is a very important research topic for the monitoring of global and regional surface water changes.
