There is a very long tradition in designing color palettes for various applications. Although color palettes have been influenced by the available colorants, starting with the advent of aniline dyes there have been few physical limits on the choice of individual colors. This abundance of choices exacerbates the problem of limiting the number of colors in a palette.
The traditional solution is that of "color forecasting." Color consultants assess the sentiment or affective state of a target customer class and compare it with new colorants offered by the industry. They assemble a limited color palette, name the colors according to the sentiment, and publish their result.
The color forecasting business is very labor intensive and difficult, thus for years computer engineers have tried to come up with algorithms to design harmonious color palettes, alas with little commercial success. Contrary to the auditory sense, there is no known physiological mechanism sustaining harmony and the term "harmonious" just has the informal meaning of "going well together."
We argue that the intellectual flaw resides in the belief that a masterful individual can devise a "perfect methodology" that the engineer can then reduce to practice in a computer program. We suggest that the correct approach is to consider color forecasting as an act of distillation, where a palette is digested from the sentiment of a very large number of people. We describe how this approach can be reduced to an algorithm by replacing the subjective process with a data analytic process.
As an increasing portion of manuscripts submitted to American journals is from Asian scientists, increasing a journal impact factor is becoming more critical

The enormous possibilities and widespread connectivity offered by the Internet and the World Wide Web has spawned multiple ways of exchanging and communicating color images. The Internet is an evolving communication system, where uses, technologies, and applications are continuously introduced by a plethora of players. Its functionality, reliability, scaling properties, and performance limits are largely unknown—albeit they span wide gamuts from optic fiber to wireless connections and from game consoles to palmtop devices, etc. To be successful in Internet imaging, users and developers must design systems in a top-down approach. The goal of this tutorial is to sort out the available standard methods so that attendees will become familiar with the different possibilities for Internet imaging; the trade-offs, issues and dependencies of each; how and when each is used; and their system implications. To this end, we systematically present the standard methods for color encoding, image compression, file formatting, protocols, and applications.

Young-Jun Yoo, Vice President of the Automotive Business and Operations Unit at Nextchip, presents the “Optimized Image Processing for Automotive Image Sensors with Novel Color Filter Arrays” tutorial at the May 2023 Embedded Vision Summit.
Traditionally, image sensors have been optimized to produce images that look natural to humans. For images consumed by algorithms, what matters is capturing the most information. We can achieve this via higher resolution, but higher resolution means lower sensitivity. To increase resolution and maintain high sensitivity, color information can be sacrificed—but in automotive applications, color is critical. In response, suppliers offer image sensors that capture color information using novel color filter arrays (CFAs).
Instead of the traditional RGGB array, these sensors use patterns like red-clear-clear-green (RCCG). These approaches yield good results for perception algorithms, but what about cases where images are used by both algorithms and humans? Can we reconstruct a natural-looking image from an image sensor using a non-standard CFA? In this talk, Yoo explores novel CFAs and introduces Nextchip’s vision processor, which supports reconstruction of natural-looking images from image sensors with novel CFAs, including RGB-IR sensors.
Rainbow Storage is a group of techniques to store digital data in some colours, colour combinations and symbols in Rainbow Format. The technique is used to achieve high-density storage. With the help of Rainbow system we would be watching full-length high definition videos from a piece of paper! The main attraction is the cheap paper. The Rainbow technology is feasible because printed text, readable by the human eye does not make optimal use of the potential capacity of paper to store data. By printing the data encoded in a denser way much higher capacities can be achieved

Color is a perceptual phenomenon that can be explored through psychometrics and modeling of attribute correlates. Color is also a cognitive phenomenon that can be researched through color naming and categorization. We begin with a review of previous research, with an emphasis on the challenges and applications of this work. Building on a large unconstrained color naming corpus collected online from over 4,000 volunteers we demonstrate the long-tail of color naming and derive an online color tool based on the thesaurus model of synonyms and antonyms.
To further improve the quality and quantity of the underlying naming corpus, we introduce two novel feedback mechanisms to the Italian version of the online color thesaurus: instance based harvesting of missing names and optional user ranking of included names. This allows a more efficient creation of a higher quality color naming corpus.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

• Text-based image retrieval: images are annotated and a
database management system is used to perform image
retrieval on the annotation
• drawback 1: labor required to manually annotate the images
• drawback 2: imprecision in the annotation process
• Content-based image retrieval systems (CBIRS) overcome
these problems by indexing the images according to their
visual content, such as color, texture, etc.
A goal in CBIR research is to design representations that
correlate well with the human visual system
