Context based object categorization: A critical survey

Carolina Galleguillos, Serge Belongie
2010 Computer Vision and Image Understanding  
Recognizing an object in an image is difficult when images present occlusion, poor quality, noise or background clutter, and this task becomes even more challenging when many objects are present in the  ...  Several models for object categorization use appearance and context information from objects to improve recognition accuracy.  ...  The majority of the context-based models include at most two different types of context, semantic and spatial, since the complexity to determine scale context is still high for 2D images.  ...

Jian-Fang Hu, Wei-Shi Zheng, Jianhuang Lai, Shaogang Gong, Tao Xiang
2016 IEEE transactions on circuits and systems for video technology (Print)  
Human action can be recognised from a single still image by modelling human-object interactions (HOI), which infers the mutual spatial structure information between human and the manipulated object as  ...  Existing approaches rely heavily on accurate detection of human and object and estimation of human pose; they are thus sensitive to large variations of human poses, occlusion and unsatisfactory detection  ...  Fig. 7 . 7 Confusion matrices of the proposed method on the Sports image, Gupta and SYSU action video datasets.  ...

Interleaved Object Categorization and Segmentation

B. Leibe, B. Schiele
2003 Procedings of the British Machine Vision Conference 2003  
The motivation behind this is that cooccurrence in the same image allows us to compensate for parts that may occur in different locations on the object.  ...  Object shapes are compared using a distance transform, which converts a binary feature map into an image where each pixel value denotes the distance to the nearest feature pixel.  ...
