Embodiment Construction
[0047] The technical solutions in the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments of the present invention. The described embodiments are only some of the embodiments of the invention.
[0048] The technical scheme that the present invention solves the problems of the technologies described above is:
[0049] The invention provides a method for detecting horizontal characters in a natural scene of a small data set based on a deep convolutional neural network. The method comprises the following steps:
[0050] Step 1: Prepare the dataset;
[0051] First obtain a dataset suitable for natural scenes with small datasets. A total of 800 data sets were used, 229 of which were from the ICDAR2013 database. Most of the image data in this library are street view images and street signs, and the images have different shades and fonts. The 271 images were crawled from the Internet, including buildi...
