![]() We could use image processing to find the colonies, count them, and then highlight their locations on the original image. For example, we might be interested in automatically counting the number of bacterial colonies growing in a Petri dish. Morphometrics involves counting the number of objects in an image, analyzing the size of the objects, or analyzing the shape of the objects. Most of the examples used focus on one particular class of image processing technique, morphometrics, but what we will learn can be used to solve a much wider range of problems. ![]() This blog aims to provide a thorough grounding in the fundamental concepts and skills of working with image data in Python. segmentation of liver and vessels from CT images.the global-scale analysis of marine plankton diversity.estimating the population of Emperor Penguins.Some examples of image processing methods applied in research include: Uses of Image Processing in ResearchĪutomated processing can be used to analyse many different properties of an image, including the distribution and change in colours in the image, the number, size, position, orientation, and shape of objects in the image, and even - when combined with machine learning techniques for object recognition - the type of objects in the image. With careful experimental design, Python code can be a powerful instrument in answering many different kinds of questions. This blog introduces an open source toolkit for processing image data: the Python programming language and the scikit-image (skimage) library. Considering the large volumes of data that can be involved - high-resolution images that take up a lot of disk space/virtual memory, and/or collections of many images that must be processed together - and the time-consuming and error-prone nature of manual processing, it can be advantageous or even necessary for this processing and analysis to be automated as a computer program. Plot a histogram of the object area distributionĪs computer systems have become faster and more powerful, and cameras and other imaging systems have become commonplace in many other areas of life, the need has grown for researchers to be able to process and analyse image data.Morphometrics - Describe object features with numbers.Masking - iterating through a co-ordinates file.Plotting single channel images (cmap, vmin, vmax).Summary of image formats used in this blog.
