The Low Income Investment Fund (LIIF) is a nonprofit community development financial institution (CDFI) that mobilizes capital and partnerships to expand access to funding for more Americans.

This repository contains the official implementation for LIIF introduced in the following paper: Learning Continuous Image Representation with Local Implicit Image Function Yinbo Chen , Sifei Liu , Xiaolong Wang

LIIF strengthens communities through affordable housing, early care and education, and flexible capital.

Since our founding in 1984, LIIF has invested $3.5+ billion through loans and grants in facilities and programs benefiting 2.5 million people. We remain deeply committed to increasing and preserving the supply of homes, child care, schools and …

2020年12月16日 · Inspired by the recent progress in 3D reconstruction with implicit neural representation, we propose Local Implicit Image Function (LIIF), which takes an image coordinate and the 2D deep features around the coordinate as inputs, predicts the RGB value at a given coordinate as an output.

2021年12月16日 · LIIF是encoder得到的图像隐式编码。 Xhr和input的坐标矩阵是不一样的，Xhr是超分结果的坐标矩阵，而input的坐标范围肯定小于Xhr（不然为啥叫超分）。所以作者的做法是：基于LIIF，使 f 预测Xhr每一个像素对应的RGB值，即求取Shr。

在本文中，提出了用于连续图像表示的局部隐式图像函数(liif)。 在liif表示中，每个图像表示为一个二维特征图，所有图像共享一个解码函数。具体地，基于输入坐标和相邻特征向量输出rgb值。

2021年9月1日 · Inspired by the recent progress in 3D reconstruc- tion with implicit neural representation, we propose Local Implicit Image Function (LIIF), which takes an image co- ordinate and the 2D deep features around the coordinate as inputs, predicts the RGB value at a given coordinate as an output.

Decades of experience. Power Forward Communities will harness decades of experience and nationwide reach to provide a unique combination of financing, market building, and community engagement strategies from big cities to small towns to rural and Tribal regions and everywhere in …
