Img.find_template function

I use the img.find_template function to find the template, but when looking for multiple templates, the speed will drop, is there any way to improve the efficiency of multiple templates?

Lenet does not run on the M7. You'll need the H7 for it. When the H7 comes out everyone will be able to run it.

H7 hardware will be released in September?

Re: Find_number function problem

That method is just experimental. It's not really usable right now since it doesn't scale the image to the right size. We plan to have full CNN support soon.

Find_number function problem

When I test the find_number function, can I only set the length and width to 28 fixed? What if I want to change this value?
