The Importance of Blur as an Image Augmentation Technique
Blog post from Roboflow
Computer vision models often struggle with real-world conditions, necessitating the deliberate introduction of imperfections like blur during training to enhance resilience. Blur, a significant imperfection, can impede image classification tasks by obscuring feature abstraction in convolutional neural networks, as noted by researchers from Arizona State University. This technique can be applied during preprocessing or image augmentation, depending on whether all or only some production images are expected to contain blur. Tools such as OpenCV and platforms like Roboflow provide methods to implement Gaussian blur, allowing for varied applications on training images, thus simulating real-world conditions. Roboflow, in particular, offers features to control and log the degree of blur applied, helping identify levels that might pose challenges during model training.
