ridgeletとは 意味・読み方・使い方

METHOD AND DEVICE FOR EVALUATING LEFT IMAGE SUCH AS FOOTPRINT USING RIDGELET TRANSFORM例文帳に追加

Ｒｉｄｇｅｌｅｔ変換を用いた足跡などの遺留画像鑑定方法及び装置 - 特許庁

The luminance value is differentiated in the arbitrary direction and applied to general Hough transformation by using the Ridgelet transform.例文帳に追加

Ｒｉｄｇｅｌｅｔ変換を用いると、輝度値を任意の方向に微分でき、一般Ｈｏｕｇｈ変換への応用が可能となる。 - 特許庁

To provide a method and a device for evaluating a left image such as footprints by which personal authentication in criminal investigation is effectively performed by performing Ridgelet transform of the left image.例文帳に追加

足跡などの遺留画像をＲｉｄｇｅｌｅｔ変換することで犯罪捜査における個人認証を有効に行うことを可能にした遺留画像鑑定方法及び装置の提供。 - 特許庁

In the Ridgelet transform, an edge on a straight line is effectively expressed, noise is effectively removed, magnification, reduction, parallel translation and rotation are easily performed in a transformation domain by nature of Radon transform for performing linear integration of a luminance value.例文帳に追加

Ｒｉｄｇｅｌｅｔ変換は、輝度値を線積分するＲａｄｏｎ変換の性質により、直線上のエッジを効果的に表現し、かつ雑音を効果的に除去でき、変換ドメイン内で拡大縮小、並行移動、回転を容易に行える。 - 特許庁

Furthermore, a Radon domain is reproduced while raising resolution of a footprint image subjected to the Ridgelet transform stepwise and pattern matching is allowed by Hough transformation since the Radon transform is equal to a parameter space of the Hough transformation.例文帳に追加

更に、Ｒａｄｏｎ変換はＨｏｕｇｈ変換のパラメータ空間と等しいため、Ｒｉｄｇｅｌｅｔ変換された足跡画像を段階的に解像度を上げながらＲａｄｏｎドメインを再生し、Ｈｏｕｇｈ変換によってパターンマッチングが可能となる。 - 特許庁
