If you want to detect the text direction and rotate your image, you should download the VGG model from BaiduyunDisk with extract code: "ass4". Note that this VGG model can only detect 0, 90, 180, 270 degrees.

python ctpn_crnn.py --CTPN_MODEL your_ctpn_path \
		    --CRNN_MODEL your_crnn_path \
		    --VGG_MODEL your_vgg_path \
		    --ADJUST_ANGLE your_choice

Or

python ctpn_densenet.py --CTPN_MODEL your_ctpn_path \
			--DENSENET_MODEL your_densenet_path \
			--VGG_MODEL your_vgg_path \
			--ADJUST_ANGLE your_choice

Detected result

CRNN result

DenseNet result

It can be seen that the method can achieve a good performance in Chinese character recognition, but achieve a bad performance in numeric character and English character. Training data is the main reason for this result. So you may want to train your own model.
