Abstract:
A method for extracting metadata through speech recognition and caption recognition of a video, a video searching method using metadata, and a recording medium recording the same are provided to extract metadata information as a speech recognition result and an opened caption recognition result, reduce archiving work time by manual work, and enable broadcasting manufacturers to manufacture contents of good quality by automatically executing contents management and index work for mass broadcasting data. A method for extracting metadata through speech recognition and caption recognition of a video comprises the following steps of: inputting the video including the metadata, and extracting a start frame and a screen conversion frame of the inputted video(110); displaying the extracted start frame and screen conversion frame as a thumbnail image, and storing the displayed thumbnail image and time information of the thumbnail image(120); recognizing a voice of a speaker according to a phoneme of a voice included in the inputted video, and converting the recognized voice data into text data before extracting a keyword from the converted text data(130); extracting a caption through caption recognition from the inputted video(140); extracting metadata and title from the keyword and caption included in thumbnail images of a start shot, an end shot and between the start shot and the end shot if the start shot and the end shot are designated by a user in the start frame and the screen conversion frame of the displayed video(150); and displaying the extracted metadata, time information of the start shot, time information of the end shot and the title(160).

Abstract:
PURPOSE: An image enhancement processing method and an apparatus for distortion correction by air particle like fog are provided to effectively eliminate scattered light into the air. CONSTITUTION: The scattered light map generation part(120) creates the atmosphere scattered light map based on the average of the first brightness signal and rate of the standard deviation. The subtraction unit(130) subtracts scattered light map from the brightness signal of Y/C transform unit(110). The edge enhancement part(140) performs the edge enhancement processing toward the brightness signal of the subtraction unit. The post processing unit(160) performs the histogram stretching about the RGB signal of the RGB transform unit(150).
