Which neural network to choose?

Question

Neural networks

In general, I want to implement one simple project, there is a bitmap array at the input, you need to recognize image variants (bitmap) with a given threshold of accuracy. There are bitmaps of different sizes for training the network at the input, after training, you need to submit a bitmap as a matrix to the input and get the percentage accuracy between all the bitmaps on which the neural network was trained. Bitmaps for training are not of the same dimension, so it may be necessary to bring them to the same size, or is it to be solved architecturally?
For this task, I think python is the best, or not?

Answer 1

Convolution .
What is a convolution ?
PS: programming language, platform and power - do not affect the ability to build any NS.
