When to use YOLO vs vanilla CNN?

I am wanting to build a computer vision model that can identify an object in an image. For example, identify the (x, y, width, height) pixel coordinates of the bounding box of somebody's hand. I know of complex object detection algorithm likes YOLO…

Is there any way to backup weights in YOLOv5 when training after a fixed number of iterations?

I want to backup weights while training YOLOv5 so that if the training stops for some reason i dont have to start all over again like in yolov3 you can mention the folder in which weights are backed up after every 100 iterations

how do I run two separate deep learning based model together?

I trained a deep learning-based detection network to detect and locate some objects. I also trained a deep learning-based classification network to classify the color of the detected objects. Now I want to combine these two networks to detect the…

how to create labels for YOLO-V1 , target bounding box while implementing from scratch?

I'm trying to implement YOLO-V1，but I got some problem when create labels. YOLO-V1 has 2 bounding box, so, when a grid has an object, how to choose which bounding box to put location information? For example: Follow YOLO paper, normalized location…

YOLOv3 Wrong Bounding Box Prediction

I trained YOLOv3 for 1 class. When I try to predict find my object in the picture it gives me wrong bounding box coordinates and shape. I've trained yolov3-tiny version with 70 608x608 images. It was working perfect. Even I trained it with CPU and…
