Yolov4 and Yolov4-Tiny #8447

Open sanjel0307 opened 2 years ago

sanjel0307 commented 2 years ago

I was just wondering is anyone able to note the distinction between yolov4 and tiny in terms of network size. i know they both use CSPDarknet but i can't seem to find any information about the size and number of layers.

See: https://www.ccoderun.ca/darkmark/Configuration.html#ConfigNew

I also have some youtube videos where I compare the results, such as https://www.youtube.com/watch?v=gPP6fh8IIAo

Interesting, it says that yolov4 has 162 layers, yet i thought it used CSP darknet as the back-end in which my thought only had 106 layers? Could you please help me understand my misunderstanding.

Hi, did you find the answer? I also would like to know the details of network used in yolov4-custom.cfg, does it use cspdarknet?

Did you look at the config files? I believe there are 84 of them. Should be obvious what uses CSP:

stephane@u2004-hankai ~/s/p/build (master)> dir ~/src/darknet/cfg/*.cfg | wc -l
84
stephane@u2004-hankai ~/s/p/build (master)> dir ~/src/darknet/cfg/ | grep csp

And, as I posted above 3 weeks ago, see this link for a bit more info on some of these config files: https://www.ccoderun.ca/darkmark/Configuration.html#ConfigNew

yes ofc! but it is not clear what yolov4 specifically use as a backbone...

I also saw the link it only states that yolov4 has 3 layers of yolo and the custom cfg is similar to it with minor differences
