description | A black and white image acquisition method accentuating color contrast according to the present invention comprises the steps of: collecting foreground and background learning data of a color image; calculating a color difference vector of a foreground and a background; calculating an Eigen vector and an Eigen value by calculating a covariance matrix of the color difference vector and performing SVD; extracting a column vector having a greatest Eigen value from a left singular vector; using each element of the column vector as a weight of an RGB converting type; and obtaining intensity of a black and white image and converting a color image into a black and white image using the obtained intensity.
본 발명 색상 대비가 강조된 흑백 영상 획득 방법은 컬러 영상의 전경 및 배경 학습 데이터를 수집하는 단계와 전경과 배경의 색상차 백터를 계산하는 단계와, 상기 색상차 백터의 코베리언스 매트릭스를 계산하고 SVD를 수행하여 아이젠 백터와 아이젠밸류를 산정하는 단계와, 좌특이 벡터로부터 아이젠 벨류가 가장 큰 컬럼 벡터를 추출하는 단계와, 상기 컬럼 벡터의 각 엘레멘트를 RGB 변환식의 웨이트로 사용하는 단계와 흑백 영상의 intensity를 구하고 상기 intensity를 이용하여 컬러 영상을 흑백 영상으로 변환하는 단계를 포함하여 이루어지는 것을 특징으로 하는 것이다. |
