Object recognition from local scale-invariant features
Articolo
Articolo
David Lowe · OpenAlex · 1999
An object recognition system has been developed that uses a new class of local image features. The features are invariant to image scaling, translation, and rotation, and partially invariant to illumination changes and a...

Spatial Pyramid Pooling in Deep Convolutional Networks for Visual Recognition
Articolo
Articolo
Kaiming He; Xiangyu Zhang; Shaoqing Ren; Jian Sun · IEEE Transactions on Pattern Analysis and Machine Intelligence · 2015
Existing deep convolutional neural networks (CNNs) require a fixed-size (e.g., 224 × 224) input image. This requirement is "artificial" and may reduce the recognition accuracy for the images or sub-images of an arbitrar...
