RecolorCloud: A Point Cloud Tool for Recoloring, Segmentation, and Conversion
Point clouds are a 3D space representation of an environment that was
recorded with a high precision laser scanner. These scanners can suffer from
environmental interference such as surface shading, texturing, and reflections.
Because of this, point clouds may be contaminated with fake or incorrect
colors. Current open source or proprietary tools offer limited or no access to
correcting these visual errors automatically.
RecolorCloud is a tool developed to resolve these color conflicts by
utilizing automated color recoloring. We offer the ability to deleting or
recoloring outlier points automatically with users only needing to specify
bounding box regions to effect colors. Results show a vast improvement of the
photo-realistic quality of large point clouds. Additionally, users can quickly
recolor a point cloud with set semantic segmentation colors.Comment: 6 Pages, 9 figures, 1 table, To be submitted to the ACM MMSys 2024

Information-theoretic approaches to atoms-in-molecules : Hirshfeld family of partitioning schemes
Many population analysis methods are based on the precept that molecules should be built from fragments (typically atoms) that maximally resemble the isolated fragment. The resulting molecular building blocks are intuitive (because they maximally resemble well-understood systems) and transferable (because if two molecular fragments both resemble an isolated fragment, they necessarily resemble each other). Information theory is one way to measure the deviation between molecular fragments and their isolated counterparts, and it is a way that lends itself to interpretation. For example, one can analyze the relative importance of electron transfer and polarization of the fragments. We present key features, advantages, and disadvantages of the information-theoretic approach. We also codify existing information-theoretic partitioning methods in a way, that clarifies the enormous freedom one has within the information-theoretic ansatz
Aplications of Neural Networks to Find the Impact of Water in Different Berry Components in Grapes
Grape juice composition during the different stages of berry growth was compared. The analytical data
collected were used to investigate the relationships between some of the different components studied in these
berries during the ripening period.
Our goal is to study, with neural networks, the impact of water availability on Vitis vinifera L. cv. Tempranillo grape
yields and juice composition over a three-year period
Las disponibilidades de tiempo en la construcción de las normas temporales del trabajo
Introducción Las transformaciones contemporáneas del tiempo de trabajo se aprecian tomando como punto de referencia la norma temporal fordista que se consolidó, en el contexto industrial, como una combinación compleja entre formas de estabilización de la mano de obra, formas de delimitación del espacio y del tiempo de trabajo y formas de racionalización tayloriana de la producción. En ese contexto, el tiempo de trabajo estaba estrictamente medido y delimitado. De esta manera Pierre Naville (1..
As disponibilidades de tempo na construção de normas temporais de trabalho
Introdução As transformações contemporâneas do tempo de trabalho avaliam-se tomando como ponto de referência a norma temporal fordista que se consolidou, no contexto industrial, como uma combinação complexa entre formas de estabilização da mão-deobra, de delimitação do espaço e tempo de trabalho e de uma racionalização tayloriana da produção. Neste contexto, o tempo de trabalho era estritamente medido e delimitado. Desta maneira Pierre Naville (1972) sublinhava a importância chave da dimensão..
