Remote sensing

In the broadest sense, remote sensing is the short or large-scale acquisition of information of an object or phenomenon, by the use of either recording or real-time sensing device(s) that is not in physical or intimate contact with the object (such as by way of aircraft, spacecraft, satellite, buoy, or ship). In practice, remote sensing is the stand-off collection through the use of a variety of devices for gathering information on a given object or area. Thus, Earth observation or weather satellite collection platforms, ocean and atmospheric observing weather buoy platforms, monitoring of a pregnancy via ultrasound, Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET), and space probes are all examples of remote sensing. In modern usage, the term generally refers to the use of imaging sensor technologies including but not limited to the use of instruments aboard aircraft and spacecraft, and is distinct from other imaging-related fields such as medical imaging.

I´m thinking if its better for my project to do remote sensing, or use some kind of a remote to move the wires around….

An article by Duglas Schweitzer

Hearnoevil Douglas Schweitzer over on his ComputerWorld blog has an article up on the proposed legislation by Senators Murphy and Stevens banning the use of social networking sites in public schools and libraries.  Unlike most of the coverage of this proposed legislation I have seen, Douglas seems to support it.  Maybe he does not realize that the way it is currently written, such sites as Wikipedia would be banned as well.  That would be a real shame, as even my young sons have started to use the Wiki for school research.  However, I have a bigger a problem with what Douglas writes.

Douglas seems to be proud that Suffolk County, Long Island (I lived in Dix Hills in Suffolk before moving to Florida, so know it well) has already banned MySpace and the like from libraries there.  I don’t know if they have also banned Wikipedia, but the real point is, Douglas does that make your children safer?  Do you think all of the sexual predators are on MySpace?  Do you honestly think cocooning your children is going to keep them safe.  There comes a point where they have to live in the real world as it is.  I am against censorship in any public forum, unless you are talking about obscenity or other illegal acts.  I think your job as a parent is to do your best to make sure you child understands right from wrong, is not a “victim” that is easily fooled by predators and that you can trust to do the right thing.  This sort of attitude reminds me of the parents who always wanted to “hide” the drug issue from their children.  You know what, those kids wound up being the biggest drug abusers. My child in second grade is already learning drugs are bad.  The philosophy is that if you have not talked to your child about drugs by the time they are in second grade, someone else has.  Same thing here. If you think banning MySpace is going to keep your kids from learning things or being exposed to predators, brother do I have a bridge to sell you. Douglas does not want his kids learning their sex-ed on the internet.  Douglas here is a news flash, your kids are going to learn about sex-ed on the internet, whether you ban MySpace or not.  In fact the internet is just todays tool to learn about sex-ed.  Douglas where did you learn about it?  Did you sit down and have the birds and bees talk with your dad or had you already been exposed by some of your more daring friends in school.  I think artificial constraints just don’t work and don’t accomplish the goals.  Better to educate children on how to use and benefit from using MySpace the right way then to ban it all together.

The other problem is today My Space, tomorrow what?  It used to be the AOL chat rooms.  Who is going to decide what my child can and cannot see.  I don’t want the US Senate (some of whom have never been on the net and don’t have a clue) or some local library board making that decision.  As a parent I reserve that right to myself. I will make that decision and stay out of my business!

Audio Brush

Hearing, analyzing and evaluating sounds is possible for everyone. The reference-sensor for audio, the human ear, is of amazing capabilities and high quality. In contrast editing and synthesizing audio is an indirect and non-intuitive task needing great expertise.

To overcome these limitations we are creating Audio Brush, a smart visual audio editing tool. Audio Brush allows to edit the spectrogram of a sound in the visual domain similar to editing bitmaps. At the core is a very flexible audio spectrogram based on the Gabor analysis and synthesis. It gives maximum accuracy of the representation, is fully invertible, and enables manipulating the signal at any chosen time-frequency resolution.

Simple audio objects are localized in time and frequency in the spectrogram. They can easily be identified visually and selected by simple geometric masks. For many audio objects, however the structures in the spectrogram are rather complex. In order to assist the user in this process, we introduced a new paradigm: Editing through the use of audio objects. Sounds recorded beforehand under controlled conditions are taken as audio objects and stored in a database. Based on audio fingerprinting and visual pattern matching algorithms they are interactively selected and used as visual and sophisticated masks.

With these new and adaptive audio analysis and editing algorithms audio can be edited in a “what you see is what you hear” style.

International Phonetic Alphabet – I can´t do it

overview

I started experimenting within different sounds in different languages and then moved on to different sounds within the expression of different emotions.

Then I started to change the sound into visuals by using emotion feelings and analyzed the voices with matrix.

Design potentials: Forms that describe sounds.

How can I translate those sounds into visuals?

Can I use the international phonetics’s for all of them?
