What we have in store

Imaging is central to scientific research ranging from microscopy to astronomy. Analysing and processing images is a field in its own right. There are a mind-boggling variety of techniques (from simple array analysis to machine learning) to process and extract information from images. This section will try to understand how an image stores data and how we can extract that information. The next chapter will deal with the technique of image segmentation. You will have to use image analysis techniques in SP2174 (The Cell) this semester. So, we need to develop the tools and tricks necessary to understand and use images for scientific measurements.
