Image Lab v1
A browser-based image processing tool — no install, no server.
Transform any image with real algorithms, instantly.
See It In Action
Here's what Image Lab looks like when you open it — clean, dark, and ready to process any image you throw at it.
👆 The interface is fully dark-themed and inspired by real dev tools. The upload panel supports JPG, PNG, WebP and GIF up to 10MB — just drag and drop your image to start.
What is Image Lab?
Image Lab is a web application built from scratch that brings classic image processing algorithms directly to your browser. Upload any image, apply transformations in real-time, and see the results instantly — no backend, no data sent anywhere, fully private.
Originally built as an academic project converting MATLAB algorithms into a real production app, it's now a clean, open tool anyone can use.
⚡ 100% client-side. Your images never leave your device. All processing happens in real-time using the HTML5 Canvas API — fast, private, and works offline once loaded.
Extract Any Color Channel
Every digital image is made of three color layers stacked together: Red, Green, and Blue. Image Lab lets you isolate each one separately, revealing hidden details and letting you understand how images are actually built.
Separating channels is fundamental in computer vision, medical imaging, and photography. With Image Lab, you can see it live — just upload an image and click.
Grayscale, Binarization & Double
Beyond color extraction, Image Lab includes several classic intensity-based transforms used in real image processing pipelines:
-
Grayscale Converts the image to shades of gray using a luminance-weighted formula. Preserves perceived brightness.
-
Binarization (Otsu's Method) Automatically finds the optimal threshold to turn any image into pure black & white. Used in OCR, document scanning, and object detection.
-
Double (Brightness Amplify) Doubles pixel intensity values, revealing detail in dark regions and simulating exposure correction.
-
Color Quantization Reduces the number of distinct colors while preserving visual fidelity. Great for compression and artistic effects.
Resize, Rotate & More
Image Lab also implements geometric transformations from scratch — not relying on browser CSS tricks, but computing pixel coordinates mathematically.
Bilinear Resize
Scales images up or down using bilinear interpolation — smooth results even at extreme ratios.
Affine Rotation
Rotates images by any angle using affine transformation matrices. Pixel-perfect, no blurring.
Upload & Export
Load any JPEG, PNG or BMP image and download the processed result instantly.
Real-Time Preview
See every transformation applied live in the canvas — no waiting, no server round-trips.
The Tech Behind It
Entirely built with modern web standards — no heavy libraries for the processing logic. Every algorithm is hand-written JavaScript running on the Canvas API.
🧠 No AI used for processing. Every algorithm — Otsu threshold, bilinear interpolation, affine matrices — is implemented manually. This is classic computer vision the way it was meant to be understood.
From Students to Professionals
Image Lab was designed to be useful for a wide range of people:
-
CS & Engineering Students Understand image processing algorithms visually, not just theoretically.
-
Photographers & Designers Quickly isolate channels, convert to B&W, or experiment with color separation.
-
Researchers & Developers Test binarization thresholds and transformations without writing any code.
-
Curious People Ever wondered what your photo looks like in only red? Now you can find out in 2 seconds.
