BREN: body reflection essence-neuter model for separation of reflection components
Optics Letters
|May 1, 2015
Summary
We introduce a new reflection color model and method to separate image reflection components. This approach is robust to noise and works across RGB and CMY color spaces without needing image segmentation.
Area of Science:
- Computer Vision
- Image Processing
- Color Science
Background:
- Separating reflection components in images is crucial for accurate color analysis.
- Existing methods often struggle with noise or specific color spaces like RGB and CMY (cyan, magenta, and yellow).
Purpose of the Study:
- To propose a novel reflection color model and an effective method for separating dichromatic reflection components from a single image.
- To develop a method that is robust to noise and applicable to a wide range of colors.
Main Methods:
- Introduced a reflection color model based on 'body essence' and 'neuter' components.
- Developed a method utilizing a Gaussian function to separate interface reflection, avoiding thresholding issues.
- The method operates on a single image without requiring region segmentation.
Main Results:
- The proposed model and method effectively separate reflection components.
- The approach demonstrates insensitivity to noise.
- It is suitable for colors in both RGB and CMY spaces, outperforming maximum chromaticity-based methods.
Conclusions:
- The novel reflection color model and separation method are effective and robust.
- This technique offers an improvement over existing methods for dichromatic reflection separation.
- The method's applicability across color spaces and noise resilience make it a valuable tool in image processing.

Reflection of Waves
4.9K
When a wave travels from one medium to another, it gets reflected at the boundary of the second medium. A common example of this is when a person yells at a distance from a cliff and hears the echo of their voice. The sound waves (longitudinal waves) traveling in the air are reflected from the bounding cliff. Similarly, flipping one end of a string whose other end is tied to a wall causes a pulse (transverse wave) to travel through the string, which gets reflected upon reaching the wall. In...

Total Internal Reflection Fluorescence Microscopy
13.8K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Three-Compartment Open Model
1.2K
The three-compartment open model is a pharmacokinetic model used to describe the distribution and elimination of drugs following extravascular administration. It comprises a central compartment representing the plasma and two peripheral compartments. The highly perfused peripheral compartment represents organs and tissues with a rich blood supply, such as the liver, kidneys, and lungs. The scarcely perfused peripheral compartment represents tissues with lower blood supply, such as adipose...
