Pairwise Similarity Knowledge Transfer for Weakly Supervised Object Localization

1 code implementation ECCV 2020 Amir Rahimi, Amirreza Shaban, Thalaiyasingam Ajanthan, Richard Hartley, Byron Boots

Weakly Supervised Object Localization (WSOL) methods only require image level labels as opposed to expensive bounding box annotations required by fully supervised algorithms.

Intra Order-preserving Functions for Calibration of Multi-Class Neural Networks

1 code implementation NeurIPS 2020 Amir Rahimi, Amirreza Shaban, Ching-An Cheng, Richard Hartley, Byron Boots

A common approach is to learn a post-hoc calibration function that transforms the output of the original network into calibrated confidence scores while maintaining the network's accuracy.

MMTM: Multimodal Transfer Module for CNN Fusion

1 code implementation CVPR 2020 Hamid Reza Vaezi Joze, Amirreza Shaban, Michael L. Iuzzolino, Kazuhito Koishida

In late fusion, each modality is processed in a separate unimodal Convolutional Neural Network (CNN) stream and the scores of each modality are fused at the end.

Local Similarities, Global Coding: An Algorithm for Feature Coding and its Applications

no code implementations24 Nov 2013 Amirreza Shaban, Hamid R. Rabiee, Mahyar Najibi

Data coding as a building block of several image processing algorithms has been received great attention recently.

From Local Similarity to Global Coding: An Application to Image Classification

no code implementations CVPR 2013 Amirreza Shaban, Hamid R. Rabiee, Mehrdad Farajtabar, Marjan Ghazvininejad

Exploiting the local similarity of a descriptor and its nearby bases, a global measure of association of a descriptor to all the bases is computed.
