Image augmentation for improvement of performance of deep learning image classifiers
Frequency Domain Filters are used for smoothing and sharpening of image by removal of high or low frequency components. Sometimes it is possible to remove very high and very low frequencies. Frequency domain filters are different from spatial domain filters as it basically focuses on the frequency of the images. It is basically done for two basic operations i.e., Smoothing and Sharpening. Our choice of filter is the Butterworth low pass and high pass filter.
