Mat open cv store rgb.
It requires quite a lot of processing time to perform necessary pipelines which could be redundant.
I considered using sqllite databases but those seem to add unnecessary complexity in.
Opencv provides all the necessary functions and overloaded operators that you need to perform all four basic operations of addition.
N dimensional dense array class.
For now i m storing the calculation result as a mat image output.
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.
Is there any other way i can store the result of multiplication output at vec3b i j 0 by creating a new matrix instead of store it as mat object.
The low level way would be to access the matrix data directly.
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.
Thus mats would be preferably stored to prevent re computation every time.
Opencv is a computer vision library whose main focus is to process and manipulate this information.
Because i need to calculate this value later and store it as matrix instead of mat will help a lot.
The class mat represents an n dimensional dense numerical single channel or multi channel array.

What is the best way to store a mat object in android.
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.
