Features

• GPU-Accelerated Shaders - Uses programmable GPU-accelerated shaders to manipulate pixels for real-time image filtering and geometric distortion.
• Texture-Based Data Pipelines - Utilizes an architecture that passes image data between processing stages as GPU textures to maximize performance.
• Image Processing - Employs the graphics processor to handle complex image transformations and blending without impacting UI performance.
• Image Filters - Implements a wide range of technical and artistic filters, including blur, luminance, and vibrance, using GPU shaders.
• Image Blending - Includes an engine for merging multiple image layers using blending modes like multiply, overlay, and screen.
• OpenGL Graphics Programming - Implements a library based on OpenGL for applying real-time graphical filters and distortions.
• Real-Time Image Filtering - Applies visual effects and color transformations to photos and live camera feeds in real-time using shaders.
• Real-Time Video Filtering - Features a processing engine that applies low-latency graphical effects to live camera feeds.
• Live Camera Processing - Provides a framework for applying real-time graphical shaders and filters directly to live camera feeds.
• Camera App Frameworks - Provides a framework for building Android camera applications with custom visual filters and real-time distortions.
• Android Image Processing - Provides a set of shader-based visual effects for modifying luminance, vibrance, and geometry within the Android ecosystem.
• GLSurfaceView Integrations - Connects the OpenGL rendering pipeline directly to the Android view system for live previews.
• Photo Editing - Offers capabilities for local image manipulation including luminance adjustment, blurring, and edge detection.
• Image Displacement Effects - Enables image shape alteration through GPU-driven refraction effects such as swirls and bulges.
• Edge Detection Algorithms - Provides mathematical operators to detect structural boundaries and outlines within digital images.
• Render-to-Texture Buffers - Implements mechanisms to capture rendering output into off-screen buffers for subsequent processing and display.
• Image Transformation Utilities - Includes utilities for adjusting image orientation and size through rotation, flipping, and rescaling.
• Render Pass Effect Pipelines - Implements a pipeline that decomposes complex visual effects into sequential render passes by chaining shaders.
