Abstract: The present invention relates to a method for size estimation by image recognition of a specific target using a given scale. First, a reference objected is recognized in an image and the corresponding scale is established. Then the specific target is searched and the size of the specific target is estimated according to the acquired scale.

Abstract: The present invention provide an automatic, frame-by-frame, rapid, and accurate search method for video clip. It comprises the following steps. First, acquire and store a plurality of videos to a storage unit. Each video comprises a plurality of frames, respectively. Then, a processing unit extracts the characteristics of the plurality of frames and gives a plurality of characteristic values. Next, the processing unit calculates a plurality of difference values between the characteristic value of each frame and that of the previous frame and between the characteristic value of the subsequent frame and that of the current frame. Store a data set, which is produced by corresponding the plurality of difference values between all frames of each video to the time axis, to the storage unit. Finally, the processing unit compares a data set of any video with a plurality of data sets of other videos and gives a search result.

Abstract translation: 本发明提供了一种用于视频剪辑的自动逐帧，快速，准确的搜索方法。 它包括以下步骤。 首先，将多个视频获取并存储到存储单元。 每个视频分别包括多个帧。 然后，处理单元提取多个帧的特性并给出多个特征值。 接下来，处理单元计算各帧的特征值与前一帧的特征值之间以及后续帧的特征值与当前帧的特征值之间的多个差值。 存储通过将每个视频的所有帧之间的多个差值对应于时间轴而产生的数据集存储到存储单元。 最后，处理单元将任何视频的数据集与其他视频的多个数据集比较，并给出搜索结果。
