In this paper, we present an efficient rectification algorithm for un-calibrated multi-view images based on SIFT (Scale-invariant feature transform) feature matching. Un-calibrated rectification is necessary for some specific occasions and we extend generic stereo pair rectification to multi-view camera array with projection shift method. We bring in SIFT algorithm to extract and match features (key...
The problem of mining single-label data streams has been extensively studied in recent years. However, not enough attention has been paid to the problem of mining multi-label data streams. In this paper, a weighted voting ensemble approach is proposed to tackle this problem. We partition the incoming data stream into sequential chunks, and use binary relevance method to transform each chunk into a...
This paper presents a new digital image watermark algorithm, which based on the second generation wavelet. The algorithm decomposes the host image by multi-resolution wavelet firstly, and then embeds watermark into low frequency part with wavelet transformation, and meanwhile embeds watermark into intermediate frequency part with threshold method. This algorithm has good robustness under some conventional...
