The invention discloses a face recognition method based on affine scale invariant feature transformation and structural similarity. The face recognition method relates to the technical field of face recognition. An operator AISFT (affine scale invariant feature transformation) is described by an image local characteristic to obtain a matching point between images; a redundant matching point is eliminated on the basis of a ''network leakage'' method; then, according to a structural similarity algorithm, the similarity based on a key point is obtained; and finally, the face recognition is realized. The face recognition method disclosed by the invention has the advantage of simplicity, easiness in realizing, correction and higher recognition rate.

The invention relates to a method for improving snooker hit rate, which solves the problem that the hitting force and position can be judged when a ball arm hits a ball in a vertical surface passing the ball center in the horizontal direction, and through the adoption of the method, the goal ratio reaches 97% above after the estimated hitting position and force by which an object ball falls into a pocket are input in a snooker table, therefore, hitting guidance for people can be provided visually. The method includes the steps as follows: analyzing the moving states of a cue ball and the object ball before and after the cue ball hits the object ball as per the discrete ball positions of consecutive frames and tracked motion trails of balls; comparing and judging the moving speed of the cue ball and the object ball before and after the cue ball hits the object ball, giving the data including the hitting position and hitting force related in a match; and performing statistics of the estimated ...

The invention relates to a CT (Computerized Tomography) image metal track prediction and artifact reduction method based on integral cosine. Aiming at metal area part cutting in a metal artifact reduction algorithm, compared with a common threshold algorithm which uses original sinogram data to reestablish images, then cuts an image domain into metal pixels and finally projects the cut metal pixels onto a sinogram domain to position a metal track, the CT image metal track prediction and artifact reduction method based on integral cosine firstly obtains various projection tracks according to a cosine projection relationship, projections on each track are added and values which are greater than a threshold are regarded as values corresponding to metal, so that the metal track is obtained. The CT image metal track prediction and artifact reduction method based on integral cosine has the advantages that the original images are not required to be reestablished, the time is greatly saved, the ...

The invention provides a method for calculating a translation vector and rotary parameters of a central point of a barbell and belongs to the field of image processing. The method provided by the invention can be used for automatically and accurately obtaining the translation vector and a rotary angle of the central point of the barbell. The method comprises the following steps of: firstly, carrying out movement region detection in a first frame image and detecting characteristic points in the barbell; then calculating a corresponding definite proportion through tracking the characteristic points on the barbell; correcting tracking errors of the characteristic points through an individual central point calculated by the minimum variance and an optimal central point calculated by an optimal statistical method; and calculating the translation vector and the rotary angle through inter-fame comparison. According to the method disclosed by the invention, the movement track and rotary parameters ...
