Chap 01: Introduction to CV

Why CV so important? over 85% of data on Internet is pixel-based, images or videos => Vision.Why is CV exploding? Sensors. All kinds of cameras everywhere. (smartphones, cars, drones, surveillances)Big Data.Dark matterson Internet. beyond human ability.

Chap 15： Convolutional Neural Networks

Chap 27: Segmentation & (Soft)Attention

Segmentation semantic segmentation : 只输出不同的类别classinstance segmentation: 即使是同一个class, 不同的个体instance, 也独立标出 (Soft)Attention Discrete locationsContinuous locations (Spatical Transformers)

multi-scale, upsampling, downsampling, deconvolution

FCN

Multi-scale

Refinement : iteratively

Upsampling

Deconv = normal conv back-propagation pass, a bad name, sounds likeinverse of conv, in fact, it meansconv transpose, orupconvolution,backward strided convor1/2 strided convolution.
