The Genetic and Evolutionary Drives behind Primate Color Vision

open access: yesFrontiers in Ecology and Evolution, 2017
Primate color vision is based on two to three cone types in the retina, each expressing a different class of visual pigment, making them the only mammals that possess trichromacy.

RGB-D datasets using microsoft kinect or similar sensors: a survey [PDF]

open access: yes, 2015
RGB-D data has turned out to be a very useful representation of an indoor scene for solving fundamental computer vision problems. It takes the advantages of the color image that provides appearance information of an object and also the depth image that ...

ACQUIRED COLOR VISION DEFICIENCY IN PARKINSON’S DISEASE [PDF]

open access: yesActa Medica Iranica, 2003
Acquired color deficiency in the tritan axis in Parkinson’s disease has already been reported, manifesting itself as impaired performance in various visual tasks. However, its clinical significance has always been controversial.

Color Homography Color Correction [PDF]

open access: yes, 2016
Homographies -- a mathematical formalism for relating image points across different camera viewpoints -- are at the foundations of geometric methods in computer vision and are used in geometric camera calibration, image registration, and stereo vision ...

The elementary representation of spatial and color vision in the human retina

open access: yesScience Advances, 2016
The origins of spatial and color vision in the human retina. The retina is the most accessible element of the central nervous system for linking behavior to the activity of isolated neurons.

A two-step method for identifying photopigment opsin and rhodopsin gene sequences underlying human color vision phenotypes. [PDF]

open access: yes, 2020
PurposeTo present a detailed, reliable long range-PCR and sequencing (LR-PCR-Seq) procedure to identify human opsin gene sequences for variations in the long wavelength-sensitive (OPN1LW), medium wavelength-sensitive (OPN1MW), short wavelength-sensitive (

Effect of chemotherapy on passenger mutations in metastatic colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Changes in passenger mutation load and predicted immunotherapy response after chemotherapy treatment. Tumor cells rich with passenger mutations have increased sensitivity to chemotherapy. Correlation of passenger mutations with neoantigen load suggests highly mutated clones promote a more effective response to immunotherapy, and therefore, first‐line ...

How we see [PDF]

open access: yes, 2008
The visual world is imaged on the retinas of our eyes. However, "seeing"' is not a result of neural functions within the eyes but rather a result of what the brain does with those images.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
