BATHROOM FLOOR
To provide a bathroom floor that can improve design.SOLUTION: Provided that a two-dimensional Fourier-transformed image of a top-view photographed image of a bathroom floor containing a plurality of convex portions is a converted image; an image obtained by multiplying the converted image by an n-th bandpass filter (n is 1 to 8) whose frequency at which the pass rate is the maximum value is 2 to the nth power is a converted image by nth band; an image obtained by inverse Fourier transforming the converted image by nth band is a pattern image by nth size; a common logarithm of a standard deviation of the brightness value of the pattern image by nth size is a pattern standard deviation by nth size; a combined length range corresponding to the passband of the n-th bandpass filter applied to the converted image when calculating the pattern image by nth size with the first to fourth largest pattern standard deviation by nth size is a pattern size range, there is provided a bathroom floor characterized in that the number of convex portions whose convex size is equal to or larger than the pattern size range is at least half of the total number of the plurality of convex portions.SELECTED DRAWING: Figure 1
【課題】デザイン性を向上可能な浴室床を提供することを目的とする。【解決手段】複数の凸部を含む浴室床の上面視の撮影画像を２次元フーリエ変換した画像を、変換画像とし、通過率が最大値となる周波数が２のｎ乗である第ｎバンドパスフィルタ（ｎは１～８）を変換画像に掛けた画像を第ｎ帯域別変換画像とし、第ｎ帯域別変換画像を逆フーリエ変換した画像を第ｎ大きさ別柄画像とし、第ｎ大きさ別柄画像の輝度値の標準偏差の常用対数を第ｎ大きさ別柄標準偏差とし、第ｎ大きさ別柄標準偏差が１～４番目に大きい第ｎ大きさ別柄画像を算出するときに変換画像に掛けられた第ｎバンドパスフィルタの通過帯域に対応した長さ範囲を合わせた範囲を柄サイズ範囲とした場合に、凸サイズが柄サイズ範囲以上である凸部の数は、複数の凸部の総数の半分以上であることを特徴とする浴室床が提供される。【選択図】図１
