Stage-Worthy Sensor Bows for Stringed Instruments
The demonstration of a series of properly weighted and balanced Bluetooth sensor bows for violin, viola, cello and bass.
متن کاملTwo different approaches for attacking BOWS
From December 15, 2005 to June 15, 2006 the watermarking community was challenged to remove the watermark from 3 different 512×512 watermarked images while maximizing the Peak Signal to Noise Ratio (PSNR) measured by comparing the watermarked signals with their attacked counterparts. This challenge, which bore the inviting name of Break Our Watermarking System (BOWS), and was part of the activi...
متن کاملPlucks and bows are categorically perceived, sometimes.
Cutting and Rosner lPerception & Psychophysics, 1974, 16, 564-570} reported that sawtooth wavetrains were perceived categorically when an array was varied in linear rise time increments. That is, rapid rise time stimuli were identified as plucked strings and slower rise time stimuli as bowed strings, and pluck-bow comparisons were relatively easy to discriminate but pluck-pluck and bow-bow comp...
متن کاملTackling BOWS with the sensitivity attack
We present our results in the first BOWS challenge (Break Our Watermarking System). There were three given digital photos containing an invisible watermark that was introduced using informed coding and embedding. The goal was to remove the watermark from the photos while keeping a minimum quality of at least 30 dB PSNR (peak signal to noise ratio). We focus on the method used to win the second ...
متن کاملA Workbench for the BOWS Contest
The first break our watermarking system (BOWS) contest challenged researchers to remove the watermark from three given images. Participants could submit altered versions of the images to an online detector. For a successful attack, the watermark had to be unreadable to this detector with a quality above 30 dB peak signal-to-noise ratio. We implemented our experiments in R, a language for statis...
