Abstract: A method, performed by a coloring apparatus, of coloring a sketch image includes adding a color pointer on the sketch image, according to an input of a user; determining an object related to a point where the color pointer is located, from among objects configuring the sketch image; and generating a colored image by coloring the determined object, based on a color of the color pointer.

Abstract: A method of completing coloring of an image based on a query regarding a color-unknown region in the image and an answer to the query, includes: generating, by using an artificial neural network, a first intermediate image in which at least one uncolored region in a primary image is colored; generating, by using the artificial neural network, a first color query regarding the at least one color-unknown region in the primary image; and generating a secondary image based on at least one of the first color query, a first answer to the first color query, and the first intermediate image.

Abstract: A deep learning-based coloring system includes a memory network configured to provide a color feature in response to a specific query and a coloring network configured to perform coloring, based on the color feature generated by the memory network. The memory network includes: a query generation unit configured to generate a query; a neighbor calculation unit configured to calculate k-nearest neighbors, based on similarities between the query and key memory values; a color feature determination unit configured to generate color features for indicating color information stored in the key memory; a threshold triplet loss calculation unit configured to calculate a threshold triplet loss, based on a comparison between a threshold and a distance between the color features; and a memory update unit configured to update a memory, based on whether a distance between a top value and a value of a newly input query is within the threshold.

Abstract: Provided is an apparatus for preventing a content leak, including: a view request receiving unit for receiving a content view request for view target content to obtain content viewer information; a marker form determining unit for determining a marker form regarding a location of the view target content where a marker for each character is added, according to the content viewer information; a marking method determining unit for determining a marking method regarding a type or order of markers added to the marker form; and a modified content generating unit for generating modified content by adding, to the view target content, one or more markers corresponding to the content viewer information, based on the marker form and the marking method.

Abstract: A method for providing contents includes receiving a selection request to view specific contents, from an electronic device; providing a plurality of items corresponding to a plurality of episodes included in the specific contents, in response to the selection request; and performing one of a first process and a second process, related to a provision of the specific episode, according to a product type of the specific episode, in response to a selection of one of the plurality of items through the electronic device.

Abstract: A method for providing contents includes receiving a selection request for specific contents, from an electronic device; and providing, to the electronic device, an episode list of a plurality of episodes which constitute the specific contents, based on the selection request for the specific contents.

Abstract: Representative image generation technology is provided. A representative image generation method according to embodiments of the present invention includes automatically generating a representative image for a relevant content by recognizing an object in the content, such as a webtoon, an illustration, multiple images related to a particular product, or a user's photograph album.

Abstract: Disclosed is a method and apparatus that may provide predetermined partial content of content provided from a content providing server to a user terminal by controlling the partial content based on an interaction of a user or synthesizing new content with the partial content, and by displaying the controlled content or the synthesized content.
