A Theory and Model of Scene Representations With Hippocampal Spatial View Cells [PDF]
Hippocampus, Volume 35, Issue 3, May 2025.ABSTRACT A theory and network model are presented of how scene representations are built by forming spatial view cells in the ventromedial visual cortical scene pathway to the hippocampus in primates including humans. Layer 1, corresponding to V1–V4, connects to Layer 2 in the retrosplenial scene area and uses competitive learning to form visual ...

Hippocampus, Volume 33, Issue 5, Page 533-572, May 2023., 2023 Abstract Hippocampal and parahippocampal gyrus spatial view neurons in primates respond to the spatial location being looked at. The representation is allocentric, in that the responses are to locations “out there” in the world, and are relatively invariant with respect to retinal position, eye position, head direction, and the place where the ...

IET Image Processing, Volume 17, Issue 2, Page 597-612, 7 February 2023., 2023 Abstract In the newest generation of video coding standard, Versatile Video Coding (VVC), a new technique called Quad Tree with nested Multi‐type Tree (QTMT) structure is introduced. QTMT significantly improves the coding efficiency, but the improvement in compression performance comes at the cost of drastically increased complexity.

A Computation Complexity Reduction of the Size Decision Algorithm in 3D‐HEVC Depth Map Intracoding
Advances in Multimedia, Volume 2022, Issue 1, 2022., 2022 A new video format called a multiview video plus depth map is recently designed as the most efficient 3D video representation. 3D‐high efficiency video coding (3D‐HEVC) is the international standard for 3D video coding finalized in 2016. In 3D‐HEVC intracoding, the depth map is an essential component, in which the depth map intraprediction occupies ...
