Hello I am applying as a GSoC student for scikit-image this year. I was a GSoC student for SimpleCV last year. I wanted to get started by implementing Blob Detection (DOG and LOG initially ). I was looking for some guidelines to start with. I would the code inside 'features' in a .py and/or .pyx file .Is there any existing piece of code lying around in scikit-image which I can use as a template ? I think it would be a good idea to keep the return value of all blob detection functions the same. They could return a class ( or a dict ) with some attributes set ( some blob detection algorithms might calculate areas as well ). Or I could just return (x,y) coordinates . Please point out if I am mistaken anywhere. Thanks Vighnesh
