Understanding Color Models: HSV, HSL, HSB, and More


HSV, HSL, and HSB are all color models that provide a way to represent colors in three dimensions, but they differ in how they represent the third dimension, and how they are used in practice.

◼︎ What is the HSV?



HSV stands for Hue, Saturation, and Value. It is a color model used to describe and define colors in terms of three dimensions: hue, saturation, and brightness.

  • Hue: Hue refers to the dominant wavelength of light that gives a color its characteristic hue. It is often represented as a circular spectrum, with red, orange, yellow, green, blue, purple, and violet arranged in a continuous loop.
  • Saturation: Saturation refers to the intensity or purity of a color. Highly saturated colors appear vivid and intense, while desaturated colors appear muted and washed out.
  • Value (also known as Brightness): Value refers to the perceived brightness or darkness of a color. A color with a high value appears light, while a color with a low value appears dark.

In the HSV color model, colors are represented as a combination of these three dimensions. For example, a bright red color might be described as having a hue of around 0-10 (on the circular spectrum), a high saturation of 100%, and a high value of 100%.

The HSV color model is often used in graphics and image editing software, as it provides a more intuitive way to adjust and manipulate colors. By adjusting the hue, saturation, and value of a color, designers can create a wide range of color variations and achieve specific color effects.

◼︎ What is the HSL?



HSL is a color model that stands for Hue, Saturation, and Lightness. It is similar to the HSV color model, but instead of using "value" to represent the perceived brightness of a color, it uses "lightness" to represent how light or dark a color appears to the human eye.

Here's a brief explanation of each dimension in HSL:

  • Hue: The hue of a color refers to its position on the color wheel, typically measured in degrees from 0 to 360. In HSL, the color wheel is arranged circularly, with red at 0 degrees, green at 120 degrees, and blue at 240 degrees. Colors between these primary colors are found at intermediate angles. Hue is often described as the "colorfulness" of a color.
  • Saturation: Saturation refers to the intensity or purity of a color, and is typically measured as a percentage from 0 to 100. A fully saturated color has no gray or white added to it, while a desaturated color appears more muted and less vivid. Saturation is often described as the "vividness" or "intensity" of a color.
  • Lightness: Lightness refers to the perceived brightness or darkness of a color, and is typically measured as a percentage from 0 to 100. A color with a lightness of 0% is completely black, while a color with a lightness of 100% is completely white. Lightness is often described as the "brightness" or "luminance" of a color.

In HSL, colors are represented as a combination of these three dimensions. For example, a bright, fully saturated red color might have a hue of 0 degrees, a saturation of 100%, and a lightness of 50%.

HSL is often used in graphic design and image editing software, as it provides a way to manipulate colors more intuitively. By adjusting the hue, saturation, and lightness of a color, designers can create a wide range of color variations and achieve specific color effects.

◼︎ What is the HSB?



HSB is a color model that stands for Hue, Saturation, and Brightness. It is similar to the HSV color model, but instead of using "value" to represent the perceived brightness of a color, it uses "brightness" to represent how bright or dark a color appears.

Here's a brief explanation of each dimension in HSB:

  • Hue: The hue of a color refers to its position on the color wheel, typically measured in degrees from 0 to 360. In HSB, the color wheel is arranged circularly, with red at 0 degrees, green at 120 degrees, and blue at 240 degrees. Colors between these primary colors are found at intermediate angles. Hue is often described as the "colorfulness" of a color.
  • Saturation: Saturation refers to the intensity or purity of a color, and is typically measured as a percentage from 0 to 100. A fully saturated color has no gray or white added to it, while a desaturated color appears more muted and less vivid. Saturation is often described as the "vividness" or "intensity" of a color.
  • Brightness: Brightness refers to the perceived brightness or darkness of a color, and is typically measured as a percentage from 0 to 100. A color with a brightness of 0% is completely black, while a color with a brightness of 100% is completely white. Brightness is often described as the "brightness" or "luminance" of a color.

In HSB, colors are represented as a combination of these three dimensions. For example, a bright, fully saturated red color might have a hue of 0 degrees, a saturation of 100%, and a brightness of 100%.

HSB is often used in graphics and image editing software, as it provides a way to manipulate colors more intuitively. By adjusting the hue, saturation, and brightness of a color, designers can create a wide range of color variations and achieve specific color effects. Note that some software applications use the terms HSB and HSV interchangeably, while others may have slight differences in how they calculate brightness.


◼︎ Similarities and Differences between HSV, HSL, and HSB


HSV, HSL, and HSB are all color models that provide a way to represent colors in three dimensions, but they differ in how they represent the third dimension, and how they are used in practice. Here are some similarities and differences between these color models:

Similarities:

  • All three models use hue and saturation to represent color.
  • They all provide a way to manipulate colors more intuitively, by adjusting the values of their dimensions.
  • They can all be used to represent a wide range of colors.

Differences:

  • HSV uses "value" to represent the perceived brightness of a color, while HSL uses "lightness," and HSB uses "brightness." This difference can affect how colors are perceived and manipulated.
  • HSL and HSB are often preferred for image editing and color correction, as they provide more intuitive control over the perceived lightness or brightness of a color.
  • HSV is often used in computer graphics and color selection tools, as it allows for easy selection of a specific hue, saturation, and brightness value.
  • HSL provides a more natural representation of colors, as it takes into account how lightness affects the perceived brightness of a color.
  • HSB and HSV are often used interchangeably in some software applications but may have slight differences in how they calculate brightness.

Overall, the choice of color model depends on the specific application and the desired effect. Designers and artists often use a combination of these color models to achieve the desired color and tone in their work.

Unleashing the Power of Data Augmentation: A Comprehensive Guide

Data Augmentation Increases Accuracy of your model — But how? ■ What is data augmentation? Data augmentation is a technique in machine learning used to artificially increase the size of a training dataset. This is achieved by applying transformations to the existing data, such as rotations, translations, scaling, flipping, etc. The idea behind data augmentation is to create new, diverse samples that can increase the robustness of the model and reduce overfitting. Data augmentation is important because many machine learning algorithms rely on large amounts of training data to learn patterns and make predictions. When a dataset is small, the model may not generalize well to new data and is more likely to overfit. By using data augmentation, we can increase the size of the training dataset and improve the model's performance.

Introduction  The paper "Visual Programming: Compositional Visual Reasoning Without Training" by Tanmay Gupta and Aniruddha Kembhavi introduces VISPROG, a neuro-symbolic system designed for complex and compositional visual reasoning tasks. Unlike traditional AI systems that require extensive task-specific training, VISPROG leverages the in-context learning capabilities of large language models like GPT-3 to generate modular programs from natural language instructions, providing a novel approach to tackling a wide range of visual tasks. Overview of VISPROG  VISPROG is a modular system that uses a few examples of natural language instructions and high-level programs to generate executable programs for new instructions. These programs are then executed on input images to obtain solutions and comprehensive, interpretable rationales. Each line of the generated program can invoke various off-the-shelf computer vision models, image processing subroutines, or Python functions, produc...
