Deformable Convolutions and LSTM-based Flexible Event Frame Fusion Network for Motion Deblurring

no code implementations1 Jun 2023 Dan Yang, Mehmet Yamac

It is also important to note that recent modern cameras (e. g., cameras in mobile phones) dynamically set the exposure time of the image, which presents an additional problem for networks developed for a fixed number of event frames.

Generalized Tensor Summation Compressive Sensing Network (GTSNET): An Easy to Learn Compressive Sensing Operation

no code implementations4 Aug 2021 Mehmet Yamac, Ugur Akpinar, Erdem Sahin, Serkan Kiranyaz, Moncef Gabbouj

For a special case where the CS operation is set as a single tensor multiplication, the model is reduced to the learning-based separable CS; while a dense CS matrix can be approximated and learned as the summation of multiple tensors.

Super Neurons

no code implementations3 Aug 2021 Serkan Kiranyaz, Junaid Malik, Mehmet Yamac, Mert Duman, Ilke Adalioglu, Esin Guldogan, Turker Ince, Moncef Gabbouj

In this article, we present superior (generative) neuron models (or super neurons in short) that allow random or learnable kernel shifts and thus can increase the receptive field size of each connection.

Representation Based Regression for Object Distance Estimation

2 code implementations27 Jun 2021 Mete Ahishali, Mehmet Yamac, Serkan Kiranyaz, Moncef Gabbouj

To the best of our knowledge, this is the first representation-based method proposed for performing a regression task by utilizing the modified CSENs; and hence, we name this novel approach as Representation-based Regression (RbR).

Convolutional versus Self-Organized Operational Neural Networks for Real-World Blind Image Denoising

1 code implementation4 Mar 2021 Junaid Malik, Serkan Kiranyaz, Mehmet Yamac, Esin Guldogan, Moncef Gabbouj

Real-world blind denoising poses a unique image restoration challenge due to the non-deterministic nature of the underlying noise distribution.

Motion Aware Double Attention Network for Dynamic Scene Deblurring

no code implementations Proceedings of the IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR) Workshops 2020 Dan Yang, Mehmet Yamac

As part of the network, event data is first used by the high blur region segmentation module that creates a probability-like score for areas exhibiting high relative motion to the camera.

Advance Warning Methodologies for COVID-19 using Chest X-Ray Images

1 code implementation7 Jun 2020 Mete Ahishali, Aysen Degerli, Mehmet Yamac, Serkan Kiranyaz, Muhammad E. H. Chowdhury, Khalid Hameed, Tahir Hamid, Rashid Mazhar, Moncef Gabbouj

The detection of COVID-19 in early stages is not a straightforward task from chest X-ray images according to expert medical doctors because the traces of the infection are visible only when the disease has progressed to a moderate or severe stage.

Convolutional Sparse Support Estimator Network (CSEN) From energy efficient support estimation to learning-aided Compressive Sensing

no code implementations2 Mar 2020 Mehmet Yamac, Mete Ahishali, Serkan Kiranyaz, Moncef Gabbouj

Indeed, a vast majority of them use sparse signal recovery techniques to obtain support sets instead of directly mapping the non-zero locations from denser measurements (e. g., Compressively Sensed Measurements).
