WebJan 8, 2024 · The identification, segmentation and detection of infecting area in brain tumor MRI images are a tedious and time-consuming task. The different anatomy structure of human body can be visualized by an image processing concepts. It is very difficult to have vision about the abnormal structures of human brain using simple imaging techniques. … WebIn particular, the combined feature vectors with PCA revealed a statistically significant improvement in classification accuracy compared to DWT (p < 0.05) and CWT (p < 0.05). Although accuracy was reduced compared to CWT for Subject 4, improved accuracy was observed for the other subjects.
