## What it is
An Android library for blurring bitmaps using Java (stack blur), RenderScript, or JNI-backed C implementations. It has been integrated into the Genius-Android project and has not been updated since 2017.

## Use cases
- blur images in an android app
- apply gaussian-like blur to bitmaps
- fast native bitmap blurring via jni
- blur large images efficiently on android
- stack blur implementation for android

## When to choose
- you need fast bitmap blurring on older Android versions with JNI acceleration
- you are already using Genius-Android and want its blur module
- you need a pure Java stack blur fallback

## When to avoid
- you need a maintained library with recent Android support
- your minSdk is modern enough to use RenderScript alternatives or built-in blur APIs
- you need blurring outside of Android

## Facets
- artifact type: library
- maturity: abandoned
- function: image-processing, graphics
- domain: image-processing, android-tools, mobile-development
- platform: jvm
- tags: blur, stack-blur, jni, renderscript, bitmap, android, mobile
