چکیده

We describe an important element of an automatic sport analysis system. This element continuously estimates the image-to-model homography from the video stream of a single camera. Here, we focus on the incremental image-to-image updating of the homography matrix, which greatly facilitates real-time operation. This updating relies on the automatic tracking of interest lines and points and on their use for robust homography estimation. Results on real video sequences are shown.

Incremental Rectification of Sports Fields in Video Streams with Application to Soccer

We describe a complete system for image rectification in sport video sequences. Relying both on geometrical properties of the field elements and on photogrammetric data, we compute an estimate of the field-to-image homography either incrementally – by inter-image data processing – or “from scratch” when direct image-model correspondences are possible. Examples are given in a soccer context.

On-Line Rectification of Sport Sequences with Moving Cameras

This article proposes a global approach to the rectification of sport sequences, to estimate the mapping from the video images to the terrain in the ground plane without using position sensors on the TV camera. Our strategy relies on three complementary techniques: (1) initial homography estimation using line-feature matching, (2) homography estimation with line-feature tracking, and (3) increm...

Robust multiplicative video watermarking using statistical modeling

The present paper is intended to present a robust multiplicative video watermarking scheme. In this regard, the video signal is segmented into 3-D blocks like cubes, and then, the 3-D wavelet transform is applied to each block. The low frequency components of the wavelet coefficients are then used for data embedding to make the process robust against both malicious and unintentional attacks. Th...

Vehicle Model Recognition in Video

Vehicle model recognition from images is one of challenging fields for supporting intelligence transport system. Existing methods only deal with vehicle in fixed view. However, in video, rotation is occurred and it decreases performance of recognition. To overcome this problem, rectification method about skew though rotated view is needed. We employ the robust license plate detection method usi...
