Video lectures for "Attention, Salience, and the Primary Visual Cortex".

this is for chapter 5 ( its free pdf file) of the book "Understanding Vision: theory, models, and data" .

This material is on attention in general, and exogenous attentional guidence by V1 in particular.

The video clips below are listed by the rough order in which their topics appear in the textbook. It is feasible, although much less convenient, to learn all the essentials of the materials without access to the textbook (which is available in many university libraries).

The next two videos can be skipped to directly go to the detailed shorter video clips

A one-hour tutorial to computer vision community at CVPR 2022, "Visual attention, visual selection, and V1 Saliency Hypothesis"

the videos listed above are more or less complete for learning the materials in chapter 5 of the book. If I add one more short video clip for this chapter, it would be for the material in section 5.7 (page 279-285: V1's role beyond saliency --- selection verss decoding, periphery versus central vision), which is mainly discussions on the boundary topic between chapter 5 and chapter 6 of the book.
