So far I\'ve implemented a gaussian blur filter entirely in the space domain, making use of the separability of the gaussian, that is, applying a 1D gaussian kernel along the rows and then along the c
I am playing with the gyro on iPhone 4, although I am settin开发者_StackOverflowg the gyro update rate to 100Hz
I want to plot the pitch of a sound into a graph. Currently I can plot the amplitude. The graph below is created by the data returned by getUnscaledAmplitude():
I try to implement Incognito k-anonymization algorithm in Java. A part of this algorithm is the frequency set construction for a given table. The columns of the table vary each time so I decided to r
I am trying to count frequency of words in a text file. But I have to use a different approach. For example, if the file contains BRAIN-ISCHEMIA and ISCHEMIA-BRAIN, I need to count BRAIN-ISCHEMIA twic
I am working on a project in which I need to be able to generate midi notes of varying frequencies with as much accuracy as possible.I originally tried to write my program in Java, but it turns out th
