We propose a method to both identify and synchronize multi-camera video recordings within a large collection of video and/or audio files. Landmark-based audio fingerprinting is used to match multiple recordings of the same event together and time-synchronize each file within the groups. Compared to prior work, we offer improvements towards event(More)
PURPOSE To review our initial experience with the holmium laser in patients with recurrent superficial bladder cancer. PATIENTS AND METHODS We treated 41 patients having 71 recurrent superficial transitional-cell tumors of the bladder between December 1994 and September 1997 using the holmium:YAG laser under local anesthesia. The laser treatment was(More)
Two patients, one with a persistent hypoglossal artery and the other with a persistent trigeminal artery, presented with transient ischemic attacks in the distribution of the posterior fossa. Both had stenosis and ulcerative plaques at the carotid bifurcation. Their symptoms were successfully relieved after carotid endarterectomy.
Wound healing requires a fine balance between the positive and deleterious effects of reactive oxygen species (ROS); a group of extremely potent molecules, rate limiting in successful tissue regeneration. A balanced ROS response will debride and disinfect a tissue and stimulate healthy tissue turnover; suppressed ROS will result in infection and an(More)
One of the major obstacles to obtaining human cells of a defined and reproducible standard suitable for use as medical therapies is the necessity for FCS (fetal calf serum) media augmentation in routine cell culture applications. FCS has become the supplement of choice for cell culture research, as it contains an array of proteins, growth factors and(More)
The Mobile Music (MoMu) toolkit is a new open-source software development toolkit focusing on musical interaction design for mobile phones. The toolkit, currently implemented for iPhone OS, emphasizes usability and rapid prototyping with the end goal of aiding developers in creating real-time interactive audio applications. Simple and unified access to(More)
We propose an interactive refinement method for supervised and semi-supervised single-channel source separation. The refinement method allows end-users to provide feedback to the separation process by painting on spectrogram displays of intermediate output results. The time-frequency annotations are then used to update the separation estimates and(More)
In applications such as audio denoising, music transcription, music remixing, and audiobased forensics, it is desirable to decompose a single-channel recording into its respective sources. One of the current most effective class of methods to do so is based on nonnegative matrix factorization and related latent variable models. Such techniques, however,(More)
