For now i m storing the calculation result as a mat image output.

Mat open cv store rgb.

Opencv has been around since 2001. What is the best way to store a mat object in android. Browse other questions tagged c opencv rgb mat or ask your own question. Opencv is a computer vision library whose main focus is to process and manipulate this information.

The overflow blog can one person run an open source project alone. The class mat represents an n dimensional dense numerical single channel or multi channel array. Thus mats would be preferably stored to prevent re computation every time. You want to add a single scalar value to all elements of a mat object you can simply use something similar to the following.

Therefore the first thing you need to be familiar with is how opencv stores and handles images. Because i need to calculate this value later and store it as matrix instead of mat will help a lot. The low level way would be to access the matrix data directly. In case the image is an rgb color image the result will be inverted.

There is a similar unanswered question here in image processing apps. It can be used to store real or complex valued vectors and matrices grayscale or color images voxel volumes vector fields point clouds tensors histograms though very high dimensional histograms may be better stored in a sparsemat. In an rgb image which i believe opencv typically stores as bgr and assuming your cv mat variable is called frame you could get the blue value at location x y from the top left this way. N dimensional dense array class.

I considered using sqllite databases but those seem to add unnecessary complexity in.
