Font detection method and system using artificial intelligence-trained neural network

A font detection device using a neural network, the font detection device comprising:

• a text input unit receiving a target text image including text;
• a resizing unit resizing a horizontal or vertical size to a reference input size according to an aspect ratio of the input target text image;
• and
• a font output unit inputting the resized target text image into a trained neural network and outputting a font of the text included in the text image,
• wherein the neural network is trained with a unit image extracted as a unit region of the reference input size from a training image generated by synthesizing a background with the text, and
• wherein the neural network comprises a convolution layer that extracts features through a convolution operation on the input target text image, a pooling layer that extracts a value representing a feature for each channel with respect to an extracted feature map, and a fully connected layer that outputs a probability for each category through an output of the pooling layer.
