Combining Appearance and Range Based Information for Multi-class Generic Object Recognition [chapter]

Doaa Hegazy, Joachim Denzler
2009 Lecture Notes in Computer Science  
First, a new object category dataset of 2D and range images of different object classes is presented. Second, a new generic object recognition model from range and 2D images is proposed.  ...  The model is able to use either appearance (2D) or range based information or a combination of both of them for multi-class object learning and recognition.  ...  However, the range data of a TOF camera suffer from large amount of noise.  ...

Range Loss for Deep Face Recognition with Long-tail [article]

Xiao Zhang, Zhiyuan Fang, Yandong Wen, Zhifeng Li, Yu Qiao
2016 arXiv   pre-print
The optimization objective of range loss is the k greatest range's harmonic mean values in one class and the shortest inter-class distance within one batch.  ...  Contrary to most of the existing works that alleviate this problem by simply cutting the tailed data for uniform distributions across the classes, this paper proposes a new loss function called range loss  ...  The the objective of designing range loss is summarized as: • Range loss should be able to strengthen the tailed data's impact in the training process to prevent poor classes from being submerged by the  ...
