RaScaNet: Learning Tiny Models by Raster-Scanning Images

no code implementations CVPR 2021 Jaehyoung Yoo, Dongwook Lee, Changyong Son, Sangil Jung, ByungIn Yoo, Changkyu Choi, Jae-Joon Han, Bohyung Han

RaScaNet reads only a few rows of pixels at a time using a convolutional neural network and then sequentially learns the representation of the whole image using a recurrent neural network.

Self-Reorganizing and Rejuvenating CNNs for Increasing Model Capacity Utilization

no code implementations13 Feb 2021 Wissam J. Baddar, Seungju Han, Seonmin Rhee, Jae-Joon Han

In this paper, we propose self-reorganizing and rejuvenating convolutional neural networks; a biologically inspired method for improving the computational resource utilization of neural networks.

Large Scale Multi-Illuminant (LSMI) Dataset for Developing White Balance Algorithm Under Mixed Illumination

1 code implementation ICCV 2021 Dongyoung Kim, Jinwoo Kim, Seonghyeon Nam, Dongwoo Lee, Yeonkyung Lee, Nahyup Kang, Hyong-Euk Lee, ByungIn Yoo, Jae-Joon Han, Seon Joo Kim

Images in our dataset are mostly captured with illuminants existing in the scene, and the ground truth illumination is computed by taking the difference between the images with different illumination combination.

A Generalized and Robust Method Towards Practical Gaze Estimation on Smart Phone

no code implementations16 Oct 2019 Tianchu Guo, Yongchao Liu, HUI ZHANG, Xiabing Liu, Youngjun Kwak, Byung In Yoo, Jae-Joon Han, Changkyu Choi

For the second issue, we define a new metric to measure the robustness of gaze estimator, and propose an adversarial training based Disturbance with Ordinal loss (DwO) method to improve it.
