## What it is
MulimgViewer is a Python-based multi-image viewer that displays many images in a single interface for side-by-side comparison, parallel selection, and stitching. It supports loading images from multiple folders, synchronized zooming of multiple regions, and saving selected or stitched images.

## Use cases
- compare images side by side from multiple folders
- browse large image datasets quickly
- stitch images vertically and horizontally
- select and save matching images from several directories
- inspect paired data like input/output image pairs
- zoom into multiple regions of images simultaneously

## When to choose
- you need to visually compare images across multiple folders in one window
- you review computer vision or deep learning dataset outputs
- you want simple image stitching with automatic saving
- you work on Windows or Ubuntu and want a free GPL-3.0 tool

## When to avoid
- you need a lightweight single-image viewer only
- you require advanced photo editing features
- you cannot tolerate bugs in the latest code, as the README warns the newest code has many bugs and recommends an older commit

## Facets
- artifact type: application
- maturity: active
- function: image-processing, gui
- domain: computer-vision, image-processing, deep-learning
- platform: windows, python, cross-platform
