BiOrthoNet: Efficient Retinal OCT Classification Using Direction‐Specific Convolutions
International Journal of Imaging Systems and Technology, Volume 36, Issue 3, May 2026.ABSTRACT Reliable interpretation of optical coherence tomography (OCT) scans is crucial for the early detection of retinal diseases. Deep learning has emerged as a promising approach for this task; however, many existing models are computationally intensive and fail to exploit the horizontal‐vertical structural organization commonly observed in retinal

Adaptive Wavelet Thresholding for Multiresolution Denoising Based on Image Size
Engineering ProceedingsHard thresholding is a common method for denoising wavelet coefficients. However, determining an optimal threshold remains challenging. Therefore, we propose an adaptive hard threshold that accounts for the size of the noisy image based on the ...
