Looking for a scientific programmer with solid background in image processing. Must be fluent in MATLAB, OpenCV + C++, or OpenCV + Python, and comfortable implementing mathematical algorithms. Experience in image registration and feature-based classification is a big plus. This is a part-time (15-25 hours/week) position for at least one month, but it may turn into an ongoing engagement for the right candidate. Smart Systems Consulting in Boston, USA, has a contract with a life sciences company that is developing a revolutionary image-analysis platform. Your role will be to implement image enhancement and analysis algorithms, and build data-handling software utilities to support a small team of physicists and computer vision experts.

I have created a non-linear constrained optimisation algorithm in excel to solve a finance problem. However, excel and the various plug-ins I have used are extremely inefficient. I now want help to write the algorithm in a more efficient language/program. The idea would be that I can understand and use the finished product. A brief description of the algorithm: There is a simple objective function/equation that needs to be maximised. There are 100 input variables which are weightings of stocks that make up a portfolio. The objective function is quadratic with respect to these inputs. There are a number of constraints placed on the model that must be satisfied for the maximised objective function (again, some are non-linear). There is also a very large dataset that feeds into the objective functions and constraints - these are mostly exogenous however there is a 100x100 matrix multiplication that can make the computation slow. Effective engagement would start with me explaining...

This micro task is about creating a PC or Web based application to perform advanced data cleansing task. We have sets of data needs to be cleaned up from certain words, and phrases and characters. We can provide maybe up to 100 words or phrases which we already identified, but in the data pool there might be up to 1000 similar patterns/words or phrases needs to be removed. It is about cleaning up excessive words from product titles and reduce them down to few words that can best describe the product. When we search for the output title in google (google shopping), it must return the exact item without any confusion. We have the source data as CSV format and it contains around 100K product titles from almost 30 different product categories. You should create an application where we can upload the source data and click "execute" button and the app should return cleaned up data for us. We already developed PHP based script but we would like to improve the outcome. We have the...
