Description

Hi~ I'm new in multimedia processing.

my goals are detecting color blob (https://github.com/opencv/opencv/tree/master/samples/android/color-blob-detection ) and recording modifed mat memory to video file(RecordActivity.java) in android device

I tried various methods, but fail to success.

(https://github.com/opencv/opencv/tree/master/samples/android/color-blob-detection ) is possible to translate to javacv style?

Please give some guides and help~

thanks

Research direction
Refer to the JavaCV documentation and the OpenCV Android sample to understand the color blob detection and recording APIs. Focus on using JavaCV's FrameGrabber and FrameRecorder classes, and OpenCV's Core.inRange and Imgproc.findContours for blob detection. Check existing JavaCV examples for guidance.
