development of object classification, localization and detec-tion techniques. 2.1. Sliding Window In the early development of face detection, researchers tended to treat it as a repetitive task of object classifica-tion, by imposing sliding windows and performing object classification with the neural networks on the window re-gion.

tensor. A color image is in fact an order 3 tensor. An image with Hrows and W columns is a tensor with size H W 3: if a color image is stored in the RGB format, it has 3 channels (for R, G and B, respectively), and each channel is a H Wmatrix (second order tensor) that contains the R (or G, or B) values of all pixels.

Four simple vector equations (or one tensor equation and an asssociated dual) describe the unified electromagnetic field and more or less directly imply the theory of relativity. The discovery and proof that light is an electromagnetic wave and unifies two fields stands to this day as one of the greatest moments in the history of science.
