The multilevel threshold tool divides an image into dark, mid, and bright regions, allowing precise brightness control by isolating different intensity ranges for customized image processing.

Multilevel Threshold

Our Multilevel Threshold tool enables precise control over image brightness by dividing it into three distinct regions: dark, mid, and bright areas. This tool is ideal for adjusting images with varying light intensities, allowing you to isolate and modify specific brightness ranges effectively.

How It Works

The tool calculates brightness levels across the entire image, identifying the darkest, middle, and brightest thirds. Sliders let you adjust the boundaries between these regions, creating a unique visual effect by emphasizing or downplaying certain brightness levels.

Features

  • Dynamic Sliders: Automatically positioned based on image brightness levels for intuitive adjustments.
  • Real-time Preview: See changes immediately as you adjust the sliders, offering a smooth and responsive editing experience.
  • Download Option: Save your processed image in PNG format with customized brightness settings applied.

Ideal Uses

This tool is particularly useful for image segmentation, creative editing, and preparing visuals for data analysis or artistic effects. By separating brightness levels, you gain greater control over contrast, shadows, and highlights, enhancing image clarity and visual appeal.

Libraries Used

  • noUiSlider: A lightweight, accessible JavaScript slider library that enables smooth and responsive control for brightness thresholds. Available at GitHub.
