Provided are image search system and methods. The image search system may include a query engine for reconfiguring a search query based on a description and an attribute of a sketch query that is input to a query image; a search engine for extracting image data that matches the search query from a database; and a display apparatus for displaying the extracted image data.

Image search system and method using descriptions and attributes of sketch queries

Provided are an image stabilizing apparatus and method thereof. The image stabilizing apparatus performs image stabilization by using both an image sensor and a motion sensor. Image distortion and movement are stably corrected by using both the position of a feature point, which is extracted by the image sensor and image processing, and the movement position of the feature point, which is predicted by the motion sensor.

Image stabilizing method and apparatus

Provided is a photographing apparatus and photographing method. The photographing apparatus includes a fish eye lens; a plurality of light emitters disposed around the fish eye lens and configured to emit light at different angles with respect to an optical axis of the fish eye lens; and an image sensor configured to receive the light emitted from the plurality of light emitters and reflected by at least one object, and convert the light into an electric signal including depth information about the object.

Photographing apparatus and method

A method of stabilizing a video is provided. The method includes detecting a feature point from a first frame; predicting a location of the feature point in a second frame based on a location of the feature point in the first frame and a predetermined parameter; detecting the feature point from the second frame; determining a distance between the predicted location and a location of the feature point detected from the second frame; and updating the parameter based on a location difference between the feature point detected in the first frame and the feature point detected in the second frame, in response to determining that the distance is within a predetermined threshold.

Method and apparatus for estimating motion in video, method and apparatus for stabilizing video, and computer-readable recording medium

A foreground extracting method is provided. The foreground extracting method includes: generating a plurality of sampling images; detecting contours from the sampling images to generate a plurality of contour images including a current frame and a previous frame; comparing first positions of a first plurality of pixels in a first decision-making area of the current frame with second positions of a second plurality of pixels in a second decision-making area of the previous frame; determining directions from the second positions to the first positions and distances between the first positions and the second positions; excluding, from the first decision-making area, at least one pixel of the first plurality of pixels in response to the distance of the at least one pixel being less than or equal to a preset critical magnitude.

Foreground extracting method and apparatus

An apparatus, a method, and a recording medium for image stabilization are provided. The image stabilization method includes receiving an image that is captured by a camera, detecting a motion of the image, predicting a motion of the image, using a Kalman filter, comparing the detected motion with the predicted motion, and updating a parameter of the Kalman filter based on a result of the comparing.

A method of shortening a video includes: determining shortened key frames by selecting one key frame for every preset time interval of a time line of the video or for every preset position interval of a camera which captures the video, from among original key frames of the video; determining event key frames from which an event is detected, from among the original key frames; determining event-preserved key frames using the shortened key frames and the event key frames; and generating a shortened video using the event-preserved key frames.

Method and method for shortening video with event preservation

An image processing system and an image processing method. The image processing system includes: an image analysis engine configured to analyze an input image and generate metadata about the input image; an indexing engine configured to structuralize and organize the metadata and generate index data based on the metadata; a search engine configured to extract index data matching a search condition and image data corresponding to the index data matching the search condition, from the input image; and a browsing engine configured to generate a heatmap based on the extracted index data and image data and display the heatmap and an image matching the search condition on a screen.

Image processing system and method

Provided are an image stabilizing method and apparatus, which are capable of performing robust operations in a moving environment. The image stabilizing apparatus includes: an image pre-processor configured to receive a current image and a reference image corresponding to the current image; a feature point selector configured to select at least one feature point corresponding to a background from a plurality of feature points, comprising the background and at least one moving object, in the reference image; a motion estimator configured to estimate a motion of a current image, based on the selected feature point in the reference image and at least one corresponding feature point, corresponding to the selected feature point in the reference image, in the current image; and an image corrector configured to generate a stabilized current image by converting the current image by using the estimated motion.
