This device can allow a user to visualize digitally the sound that they are emitting from a certain wind instrument as they play a certain melody. For this report, bamboo pipes were utilized. Permitting the user to visualize digitally their wind based music, will aid designers and developers of music couches, because it opens a door for a new range of music couches focused on wind based instruments. It will allow for wind based instruments to participate in a new type of musical interaction that had before not yet been reached. The system is also capable of reproducing in an eolic form any digital music signal that is given to it. Recordings from nature were made and digitalized and feed to the system, the system was capable of reproducing the sound of waves, and thus also permitting for another novice musical interaction.","PeriodicalId":236039,"journal":{"name":"2010 20th International Conference on Electronics Communications and Computers (CONIELECOMP)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134036899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The program is completely graphic, made on J2ME technology, and is executable in any mobile phone. The program communicates wirelessly with a Bluetooth module that receives the instructions made by the user, these sequences can be prerecorded or a new sequence, instructions are received and processed by the microprocessors 80C51; one allows save the sequence and allows the traffic to ZigBee (modules used by its low power consumption), the second microcontroller is responsible for controlling power section that is reflected in the light intensity.

The basic idea is to project a sinusoidal fringe pattern with a known spatial frequency on the object to digitize, and then a vision system captures and processes the image to obtain the object's depth information. First, the fringe pattern is projected on a reference plane then an image is acquired, later the object to digitize is placed in front of the reference plane and then another image is acquired. The fringe pattern is distorted due to the object's irregular shape. One of the main difficulties to face is the high frequency content in the unwrapping process. This effect can be minimized by knowing the spatial frequency and its multiples. Here, we propose to implement global and local phase unwrapping algorithms to overcome the high frequency problems. These algorithms are part of the modified Fourier Transform Profilometry Method (FTP), where the resulting phase difference of the acquired and processed images have the information of the object's depth. Some tests with computer generated and real objects with different geometries are carried out to verify the proposed methodology, considering the factors that mostly affect the method.","PeriodicalId":236039,"journal":{"name":"2010 20th International Conference on Electronics Communications and Computers (CONIELECOMP)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129881969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The expanded histogram along with the variance levels are fed into a thresholding finding algorithm based on partitioning the interval (histogram) in an optimal way using dynamic programming with an entropy-based cost function. Compared with many existing methods, simulations on a range of images show good results. The effectiveness of the algorithm is shown even in the presence of low to moderate additive Gaussian noise levels.","PeriodicalId":236039,"journal":{"name":"2010 20th International Conference on Electronics Communications and Computers (CONIELECOMP)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116734104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
