Pneumonia detection using deep convolutional networks is an important application of deep learning in the field of medical image analysis. In this approach, a Convolutional Neural Network (CNN) is used to classify chest X-ray images as either normal or indicating the presence of pneumonia. The CNN is trained on a dataset of labeled images, learning to recognize patterns associated with pneumonia, such as infiltrates or consolidation in the lungs. The following three problems are addressed in this research work. Initially, the images with noise are not suitable for prediction and most of the filtering techniques generate the loss in the data and over smoothening of images. It can be resolved by the proposed Perona-Malik (PM)- Multisampling technique. It preserves the edges and smoothens the different region of image parallel manner. Second, the class imbalance problem is addressed by using synthesized …
