An image captioning model was proposed in 2015, citing inspiration from the seq2seq model. [ 25 ] that would encode an input image into a fixed-length vector. Xu et al (2015), [ 26 ] citing Bahdanau et al (2014), [ 27 ] applied the attention mechanism as used in the seq2seq model to image captioning.
In addition, the scope of attention, or the range of token relationships captured by each attention head, can expand as tokens pass through successive layers. This allows the model to capture more complex and long-range dependencies in deeper layers. Many transformer attention heads encode relevance relations that are meaningful to humans.
A time attention layer is where the requirement is ′ =, ′ = instead. The TimeSformer also considered other attention layer designs, such as the "height attention layer" where the requirement is ′ =, ′ =. However, they found empirically that the best design interleaves one space attention layer and one time attention layer.
In 1943, Warren McCulloch and Walter Pitts proposed the binary artificial neuron as a logical model of biological neural networks. [11]In 1958, Frank Rosenblatt proposed the multilayered perceptron model, consisting of an input layer, a hidden layer with randomized weights that did not learn, and an output layer with learnable connections.
A structured-light 3D scanner is a device used to capture the three-dimensional shape of an object by projecting light patterns—such as grids or stripes, onto its surface. [1] The deformation of these patterns is recorded by cameras and processed using specialized algorithms to generate a detailed 3D model .
Visual temporal attention is a special case of visual attention that involves directing attention to specific instant of time. Similar to its spatial counterpart visual spatial attention , these attention modules have been widely implemented in video analytics in computer vision to provide enhanced performance and human interpretable ...

In computer vision, 3D object recognition involves recognizing and determining 3D information, such as the pose, volume, or shape, of user-chosen 3D objects in a photograph or range scan. Typically, an example of the object to be recognized is presented to a vision system in a controlled environment, and then for an arbitrary input such as a ...
