In recent years, deep learning methods utilizing convolutional neural networks have been extensively employed in hyperspectral image classification (HSI) applications. Nevertheless, while a substantial number of stacked 3D convolutions can indeed achieve high accuracy, they also introduce significant parameters to the model, resulting inefficiency. Furthermore, such intricate models often exhibit limited accuracy when confronted with restricted sample data, i.e., small problems. Therefore,...

Advances in methodologies and tools often lead to new insights into cardiovascular diseases. Intravascular ultrasound (IVUS) is a well-established diagnostic method that provides high-resolution images of the vessel wall atherosclerotic plaques. High-frequency (>50 MHz) enables spatial resolution IVUS approach optical imaging methods. However, penetration depth decreases when using higher frequencies due greater acoustic attenuation. An improves would, therefore, be major clinical...
