A method and apparatus are provided for generating a character collage message. A character is recognized from an image. A region is extracted from the image to create a character image. The region includes the recognized character. The created character image is stored in a memory. At least the character image is output to an output unit as the character collage message in accordance with input of one or more characters through an input unit. At least one of the one or more characters corresponds to the character image, and the character image is output to the output unit as a substitute for the at least one of the one or more characters.

A character region extracting apparatus and method which extract a character region through the calculation of character stroke widths are provided. The method includes producing a binary image including a candidate character region from an original image; extracting a character outline from the candidate character region; acquires character outline information for the extracted outline; setting a representative character stroke width and a representative character angle in each of the pixels forming the outline, based on the character outline information; and determining a character existing region in the candidate character region by confirming the ratio of effective representative stroke widths and effective angles as compared to the entire length of the outline. Accordingly, it is possible to efficiently determine whether one or more characters exist in the candidate character region.

Character region extracting apparatus and method using character stroke width calculation

Provided is an apparatus and method for generating an image for character region extraction. Upon input of an original image, a candidate character image is generated from the original image and a plurality of binarization maps for similar colors are generated from the generated candidate character image. A binarization map including a background region is selected from among the plurality of generated binarization maps, and the background region of the selected binarization map is expanded. The expanded background region is inverted to generate an image including a character region, thereby generating an image for accurately extracting the character region without missing a boundary portion of a character.

An apparatus and method for retrieving a moving picture using a descriptor of a tree-structured moving picture index. If the user starts a query for the retrieval of information, a decoder sends an in-index highest-order key frame number, in-index edge information and an intra-layer threshold value list of a tree-structured moving picture index descriptor stored therein to a server environment. Then, the server environment reads a key frame number and sends it to the decoder. The decoder sends a feature vector designated by the key frame number to the server environment. Subsequently, the server environment first compares the designated feature vector with a query feature vector and, thereafter, the compared result with a threshold value and retrieval precision desired by the user to determine whether the key frame number is concerned with a query picture. If the key frame number is concerned with the query picture, the server environment transfers the retrieved result to a user environment. This processing is sequentially carried out by key frame numbers.
