tagging the images of bank cheque

Tagging the images which have the bank cheque. The output has a tag of cheque or non-cheque, and a confidence score between 0 and 1.

Input	Output
	{ 'tag': 'cheque', 'score': 0.7404399 }
	{ 'tag': 'non_cheque', 'score': 0.7928494 }
	{ 'tag': 'non_cheque', 'score': 1.0 }

Installation

to install the cheque tagger model, you need Python 3.7.7. Then you can download the code and pre-trained models as follows

git clone https://github.com/yanliang12/cheque_detection.git

cd cheque_detection

pip3 install -r requirements.txt

wget https://github.com/fchollet/deep-learning-models/releases/download/v0.4/xception_weights_tf_dim_ordering_tf_kernels_notop.h5

download the pretrain model of cheque detection from the following url

Using

Test with a positive case

to use the model to tag the image, download the an image of cheque by

wget https://upload.wikimedia.org/wikipedia/commons/thumb/3/3c/Sample_cheque.jpeg/1200px-Sample_cheque.jpeg

you can check how the image looks like

then run the test code

from  cheque_tagging import cheque_tagging

cheque_tagging("1200px-Sample_cheque.jpeg")

you will see

{'score': 0.7404399, 'tag': 'cheque'}

Test with a negative case

as a negative example, you can downloand a non-cheque image, say, my lovely campus photo, by

wget https://www.ilwindia.com/wp-content/uploads/2019/08/Heriot-Watt-University-Dubai-1.jpg

which looks like

and then run the code to do the tagging

cheque_tagging("Heriot-Watt-University-Dubai-1.jpg")

and you get the followig result because there is no cheque in the image

{'score': 1.0, 'tag': 'non_cheque'}

Training of the model

I trained this model from a data set of 536 cheque images and 38996 non-cheque images. This data set is collected by myself. The training is conducted over a GPU of Ali Cloud. The epoch number is 20, and the accuracy over the training set is 0.9984.
