How to create a custom object detection classifier

Hi, I need to detect objects from the captured frames of the esp-eye. In order to do that, I have trained a tensorflow model following this tutorial https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/training.html and as I can see here https://www.esp32.com/viewtopic.php?p=471...

Re: Building a new classifier for the ESP WHO

When you have finished training the model with some popular frameworks like tensorflow, you can then implement the inference process to the ESP related devices. The model structure is easy to implement as we have provided some common operations and you can also rewrite what you need. The model coef...

How to change from face detection to other own trained object detection

Hi, I am using the esp-eye with the esp-who project. I have noticed that it is using the dlib for the face detection training, but I need to have a different object detection. I have successfully trained another svm with the dlib library on my Ubuntu host pc, but it is not clear how can I use the tr...

How to compile DLib for a ESP32 project?

Hi, I want to use the following library http://dlib.net/ (dlib, version 19.18) in order to use neural networks on the ESP32. But I am facing hard times while trying to compile the library in order to be used in a ESP-IDF project. What I have tried to do is: - Just extracting the library sources (.h ...

Why it is not possible to use PIXFORMAT_RGB888 with higher resolutions than QVGA?

I need to scan some barcodes using the ZXing library (C++ porting) and I cannot capture and decode images (RGB888) with resolutions higher than 320x240 (QVGA), which causes panics and overflows on the ESP-WHO. Why there is this limitation? I need to capture at least XGA (1024x768) images using RGB88...

Re: Error while trying to update the firmware via OTA

I think I have the latest ESP32 IDF (3.0.8). The partition table is the default "Factory app, two OTA definitions" (0x8000 offset of partition table), and I've changed the serial flasher configuration of the flash size to 8MB. I've managed to update the firmware with a .bin file of 759 KB (the origi...

Error while trying to update the firmware via OTA

Hi, I am trying to create a bluetooth SPP system with a ESP32 (I am following the "ble_spp_server" example). I need to find a simple way to update the firmware and I am also following the "simple_ota_example" example. What I have done so far has been to take the original "ble_spp_server" example and...
