Glimpse is a C++ library that provides easy-to-use abstractions for OpenCV applications. Primarily for developers new to image processing and computer vision, glimpse allows users to setup image processing systems rapidly and conveniently on desktop and embedded (using Raspberry Pi) platforms. Glimpse is licensed under the MIT license and is free to use for personal, educational, and commercial purposes.
Glimpse provides many useful functions:
- One-line image filtering and transformation functions
- API for processing video using custom filters and viewing results
- Useful debugging tools for OpenCV development, e.g. allowing the printout of matrix information
For example, translating an image using bare OpenCV requires the following code:
Mat input = imread("test.jpg");
int offsetx = 10;
int offsety = 15;
Mat output;
Mat trans_mat = (Mat_<double>(2,3) << 1, 0, offsetx, 0, 1, offsety);
warpAffine(input,output,trans_mat,input.size());Using Glimpse, this transformation is trivial:
Mat input = imread("test.jpg");
Mat output;
Translate(input, output, 10, 15);##Live Video Processing Glimpse is useful for testing your own image processing alorithms in realtime. For example, to compare the processed and original video streams directly from your webcam, a user can define their own processing function:
void MyFilter(Mat &input, Mat &output)
{
// process image
...
}and have it run with a given framerate on their webcam video in a single line:
LiveVideoCompare(MyFilter);This code will open up two windows, one streaming the original video and the other streaming the processed video.
##Quick Start
Glimpse source code is provided in the Source folder. Use the compiler of your choice to self-compile the library, or add the source code directly to your project.
##Known Issues
Glimpse is still in active development, and new features are on the way. Certain functions only support 8-bit unsigned char images, and support for floating-point images is in development.
