In this tutorial, we will discuss Image Processing in Python using the core scientific modules like NumPy and SciPy. Right now we are using only image data (i.e., X-rays) better automatic COVID-19 detectors should leverage multiple data sources not limited to just images, including patient vitals, population density, geographical location, etc. The following paper presents the most comprehensive analysis of transfer learning using popular ImageNet architectures and ImageNet pretrained weights on chest X-ray dataset - CheXtransfer: Performance and Parameter Efficiency of ImageNet Models for Chest X-Ray Interpretation License. Typical tasks in image processing include displaying images, basic manipulations like cropping, flipping, rotating, etc., image segmentation, classification and feature extractions, image restoration, and image recognition. And thats exactly what I do. namely by selling fake COVID-19 test kits. Image loaded as chest_xray_image. The Pi may need to restart after this process. For converting image to gray, OpenCv package of python has been used. It really helped me to understand the image processing deeper. Python is one of the widely used programming languages for this purpose. Brand new courses released every month, ensuring you can keep up with state-of-the-art techniques The most critical part of image processing is done when an X-ray machine is manufactured, but further processing is required. I've additionally included an area filter. After that, you can apply a heavy morphological chain to produce a good mask of the object. Therefore developing an automated analysis system is required to save medical professionals valuable time. High quality, peer reviewed image datasets for COVID-19 dont exist (yet), so we had to work with what we had, namely Joseph Cohens GitHub repo of open-source X-ray images: From there we used Keras and TensorFlow to train a COVID-19 detector that was capable of obtaining 90-92% accuracy on our testing set with 100% sensitivity and 80% specificity (given our limited dataset). There are 5,863 X-Ray images (JPEG) and 2 categories (Pneumonia/Normal). I have many x-ray scans and need to crop the scanned object from its background noise. [1] The Hounsfield unit is named after the famous Sir Godfrey Hounsfield, who has part of the invention of Computer Tomography and was awarded the Nobel Prize for it.
