What is YOLO?
YOLO stands for You Only Look Once
YOLO is an algorithm that uses neural networks to provide real-time object detection. This algorithm is popular because of its speed and accuracy. It has been used in various applications to detect traffic signals, people, parking meters, and animals.
With the timeline, it has become faster and better, with its versions named as:
YOLO V1
YOLO V2
YOLO V3
YOLO V4
YOLO V5
YOLO V2 is better than V1 in terms of accuracy and speed.
YOLO V3 is not faster than V2 but is more accurate than V2 and so on.

How the YOLO algorithm works?
YOLO algorithm works using the following three techniques:

1- Residual blocks: image is divided into various grids. Each grid has a dimension of n X n
2- Bounding box regression
3- Intersection Over Union (IOU) : YOLO uses IOU to provide an output box that surrounds the objects perfectly.

hello mam I am facing this issue
i am working on google collab and followed almost he same code till 16:21 and the last code which i tried to run was

Output error is

AttributeError Traceback (most recent call last)
in <cell line: 1>()
----> 1

in load_weights(self, model)
25 for i in range(106):
26 try:
---> 27 conv_layer = model.get_layer('conv_' + str(i))
28 print("loading weights of convolution #" + str(i))
29

AttributeError: 'function' object has no attribute 'get_layer'
please help me solve this error as i have tried searching it everywhere but not getting any solution for it

Good explanation about the stressful architecture. Get an overview of the Yolo research paper by looking at this very easily.

i want to ask you if this code you do it by your self and how much time it takes and is it important to code like this and not using libraries like ultralytics and mediapipe?

Thank you very much Aarohi, this is the only tutorial I was able to find that actually teaches YOLO implementation and structure step by step whereas other videos all focus on simply building and training from the get go. Quick question, is this applicable for yolov4 by updating the weights used?

Thank you very much for the tutorial. I have a question with regards to preparing my dataset. My object is of a single class only (starfish). There are images with and without the starfish in the images. For the images without the starfish, do you know how should I prepare the annotation for these images?

Hello, the pre-trained weights that you used are from the COCO dataset right? Can I use from the Image Net or are there pre-trained weights available for the Image Net?

Thanks !!
