Some common questions

[lucasjinreal]

Hi, this is a really wonderful try in rust. But for a DL user I mainly focus only on some core functions like:

• resize
• cvtColor
• video open/write
• image open/write

So, just wonder, how does the performance compare with opencv? for example, the resize sometimes is non-crutial since it time-costing ,in opencv, it using SIMD for accelerations, does cv able to do so?

cv is currently more like a collection of various crates with glue to make them work together in addition to MVG primitives and algorithms. The ndarray-vision crate is where some of the image processing algorithms live. You also will find some in image and imageproc. Those two are not maintained by us, but I would look at their repo to see how they are doing it. I believe ndarray, which we are currently using for image processing of this sort, does have some SIMD support.

I would not consider cv to be useful for you if you are doing only image processing. Use the crates I mentioned above. cv is currently really only useful for MVG algorithms, and even then only a limited subset. I haven't had much time recently to maintain everything, so some of the dependencies are likely out of date as well. Best of luck!
