Dynamic Plasmonic Pixels

ACS Nano, 2019
Information display utilizing plasmonic color generation has recently emerged as an alternative paradigm to traditional printing and display technologies. However, many implementations so far have either presented static pixels with a single display state or rely on relatively slow switching mechanisms such as chemical transformations or liquid crystal

Pixel-Based Swallow Measurements: Correcting Nonsquare Pixels

Journal of Speech, Language, and Hearing Research, 2023
Purpose: This research note illustrates the effects of video data with nonsquare pixels on the pixel-based measures obtained from videofluoroscopic swallow studies (VFSS). Method: Six pixel-based distance and area measures were obtained from two different videoflouroscopic study ...

Not All Pixels Are Matched: Dense Contrastive Learning for Cross-Modality Person Re-Identification

ACM Multimedia, 2022
Visible-Infrared Person Re-Identification (VI-ReID) has become an emerging task for night-time surveillance systems. In order to reduce the cross-modality discrepancy, previous works either align the features via metric learning or generate synthesized ...

The Sound of Pixels

European Conference on Computer Vision, 2018
We introduce PixelPlayer, a system that, by leveraging large amounts of unlabeled videos, learns to locate image regions which produce sounds and separate the input sounds into a set of components that represents the sound from each pixel.

An Image is Worth More Than 16x16 Patches: Exploring Transformers on Individual Pixels

International Conference on Learning Representations
This work does not introduce a new method. Instead, we present an interesting finding that questions the necessity of the inductive bias of locality in modern computer vision architectures.

Pixellated circle

Applied Optics, 2018
For applications in optical systems it is often necessary to represent a circular aperture in a pixellated form. An objective parameter is introduced that is a measure of how well an approximate circle can be generated from a small array of square pixels. Both filled circles (disks) and rings are considered.
