this is an android project write in kotlin which detect paper or rectangle by opencv, you can take a picture and crop it

Android example of document scanning with OpenCV featuring edge detection, perspective correction, and image enhancement. Demonstrates implementation of camera preview, image processing, and OCR integration for document scanner applications.

Project of computational mathematics, image processing, eliminating the noise of an image, reflection of an image and canny filter

A Java program for detecting edges in an image using the Canny method.

An android app that shows the edges and light sources in the live feed from the phone's camera

An android app made to test OpenCV libs on Android devices. It operates on images acquired by camera. Processes: rgb to gray, gray to canny or inrange->erosion->dilatation->detecting contours and then rotated rectangles->drawing rectangles with text info about their size. Parameters of processes steered by trackbars.

Neural network and fuzzy logic based plugins for imagej

Java implementation of Sobel edge detection

SketchIt is a an interactive, media manipulation software applying fundamental computer vision/edge detection algorithms to media for both educational and artistic purposes.

Java library to detect edges in images using the Canny algorithm with variable parameters.

An android app developed with Java and OpenCV which shows us the normal camera view and the edge view using the Canny edge detector algorithm.
