Claim 0:
1. A convolutional artificial neural network-based recognition method comprising:
a first step of registering, by a content provider, an image target and content in a searcher of a K-D tree structure of a server;
a second step of photographing, by a user of a mobile device, an object with a camera to receive the content registered in the first step and processing, by the mobile device, acquired image and video data by layers LI to L6 corresponding to lower layers of a convolutional artificial neural network;
a third step of performing, by the server, operations of receiving the data processed in the second step, processing the data by layers L7 to L12 corresponding to intermediate and upper layers of the convolutional artificial neural network, determining a main direction of the acquired image and video data, and reproducing a rotation-invariant feature;
a fourth step of transmitting, to the K-D tree searcher f of the server, an FC layer value of a fully-connected layer of the convolutional artificial neural network in the data processed in the third step to search for a nearest target registered by the content provider;
a fifth step of comparing similarity of the nearest target with a threshold value and determining whether the target search is successful; and
a sixth step of transmitting target-content combination information to the mobile device and reproducing content linked to the searched object.
