Aerial images and ground-level images are two major types of image sources used by many existing image-based urban 3D modeling approaches. Due to the rapid development on hardware and camera technologies, panoramic images have become widely accessible and they have many advantages in supporting the 3D reconstruction tasks. In this paper, we have proposed an automatic image registration approach to...
In this thesis, we propose a discrete wavelet transform (DWT) based audio watermarking (DAW) for mobile ad hoc network (MANET). With the discrete wavelet transform (DWT), the audio signal can be transformed into frequency domain ranging from low frequency to high frequency. Besides, the high frequency spectrum is less sensitive to human ear. That is the reason why the high frequency component is usually...
