What are some tips for optimizing STM32 microcontrollers for image processing tasks?

[DexterHale]

I'm working on a mobile app that involves image processing and I'm considering using an STM32 microcontroller. Does anyone have experience with optimizing these for image editing tasks? I've been exploring photo editing apps like Meitu and would love to hear how similar capabilities can be achieved with STM32. Any insights would be helpful!

Hello @DexterHale ,

I am quite confused by your question. I don't understand the relation between a STM32 and a mobile app. Can you elaborate? Do you think of developing a device for smartphone and creating a mobile app?

 

Have a good day,

Julian

I’m developing a mobile app for image editing, and I’m exploring whether certain image processing tasks (like filtering or compression) can be offloaded to an external STM32 microcontroller.

Hello @DexterHale ,

 

This forum is more focused around AI, you may be interested to ask the MCUs community instead like this one:

STM32 MCUs Products - STMicroelectronics Community.

 

But here is some information that could be useful:

For the AI part, you can take a look at ST Model Zoo for image classification of object detection.

For hardware, I think bigger STM32 are more adapted for image processing, but I may be wrong. Also, you can take a look at this article about a product that ST will release: STM32N6: Get a sneak peek at the future of AI-powered MCUs

 

While looking for some kinds of computing acceleration that should be useful for image processing, I encountered terms like DSP (Digital signal processing: STM32N6: Get a sneak peek at the future of AI-powered MCUs) and Chroma-ART accelerator: How to use Chrom-ART Accelerator to refresh an LCD-TFT display on STM32 MCUs - Application note)

This may be useful but as I said, you better ask a more hardware related forum of the ST Community.

 

Have a good day

Julian
