    • When positive image similarity (degree of training image similarity between input image features and those of positive training image) is higher than a predetermined first threshold, image orientation determination decision section determines input image orientation. When negative image similarity (degree of training image similarity between input image features and those of a negative training image) is not lower than a predetermined second threshold value, the image orientation determination decision section does not determine input image orientation. When the image orientation determination decision section determines the orientation of the input image, image orientation determination section calculates orientation similarity reflecting similarity between input image features and those stored in orientation-specific features storage section. If the calculated orientation similarity satisfies a predetermined condition, the image orientation determination section determines input image orientation according to positive training image orientation related to the image features stored in the orientation-specific features storage section.
    • 当正图像相似度(输入图像特征与正训练图像的训练图像相似度)高于预定的第一阈值时,图像取向判定部确定输入图像取向。 当负图像相似度(输入图像特征与负训练图像的训练图像相似度的程度)不低于预定的第二阈值时,图像取向确定判定部不确定输入图像取向。 当图像取向确定部分确定输入图像的方向时,图像取向确定部分计算反映输入图像特征与存储在方位特征特征存储部分中的相似度的取向相似度。 如果计算出的方向相似度满足预定条件,则图像取向确定部根据与存储在方向特征特征存储部中的图像特征相关的正训练图像取向来确定输入图像取向。

    • Region dividing means (3) divides an inputted image by color or edge. Partial feature value providing means (4) extracts visual feature values of the divided region. Area sorting means (5, 6) sorts the feature values of the divided regions and part feature values (32) which are visual features of the parts into which an object is divided in order of area of the region. Part matching means (7) selects the part feature value (32) which the region of the largest area has, selects a visual feature value which the divided region of the largest area has out of the divided regions whose similarities are not calculated, calculates the similarity of the selected visual feature value, and extracts candidate regions. If the visual feature value of the joined region formed by combining the candidate regions is similar to the visual feature value of the whole object stored in storage means (2), the joined region is treated as a region similar to the object.
    • 区域划分装置(3)通过颜色或边缘划分输入的图像。 部分特征值提供装置(4)提取分割区域的视觉特征值。 区域分类装置(5,6)按照该区域的面积顺序对分割区域的特征值和作为对象划分的部分的视觉特征的部分特征值(32)进行排序。 部分匹配装置(7)选择最大区域的区域的部分特征值(32),选择最大区域的划分区域在不计算相似度的划分区域之外的视觉特征值,计算出 所选视觉特征值的相似度,并提取候选区域。 如果通过组合候选区域形成的连接区域的视觉特征值与存储装置(2)中存储的整个对象的视觉特征值相似,则将接合区域视为与对象相似的区域。

    • An outboard motor that is capable of reducing a trolling noise includes an engine which has a crank shaft extending in an up-down direction; a drive shaft extending downward from the crank shaft and including a torsion bar spring; a propeller shaft; a propeller provided in the propeller shaft; a forward/backward switching mechanism arranged to connect the drive shaft and the propeller shaft with each other; and a vibration damper which includes a first cylindrical body and a second cylindrical body which are penetrated by the torsion bar spring. The first cylindrical body and the second cylindrical body are coaxial with each other. The first cylindrical body has its upper end portion connected with an upper end portion of the torsion bar spring whereas the second cylindrical body has its lower end portion connected with a lower end portion of the torsion bar spring. A viscous fluid is filled between the first cylindrical body and the second cylindrical body.
