This document discusses various pixel processing techniques in image processing, including point operations, look-up table (LUT) operations, and inhomogeneous point operations. Point operations modify pixel values based only on the pixel value, while inhomogeneous operations also consider pixel position. LUT operations provide an efficient way to implement homogeneous point operations using a lookup table rather than individual calculations. Specific techniques covered include thresholding, adaptive thresholding, illumination correction, and windowing.

A Simple Method to Build a Paper-Based Color Check Print of Colored Fabrics b...CSCJournals
An open loop color management system is implemented to reproduce an analog color of a set of colored fabrics by a digital inkjet printer. A tetrahedral interpolation technique is designed for mapping between device-dependent (RGB) and device-independent (CIELAB) color spaces. A set of 3164 color patches are used as training set in 3-D LookUp Table (LUT) to characterize the color printer. Then, the designed color management system is examined by the colorimetric reproduction of a set of 30 colored fabrics using the conventional inkjet printer. The performance of the system is numerically evaluated by measuring the color difference values between the original and the reproduced samples. The results showed that the color reproduction system appropriately works for both groups of samples located inside the color gamut of output device, i.e. printer, and those out of gamut samples while the later logically leads to greater errors.

Developing visual material can help to recall memory and also be a quick way to show lots of information. Visualization helps us remember (like when we try to picture where we’ve parked our car, and what's in our cupboards when writing a shopping list). We can create diagrams and visual aids depicting module materials and put them up around the house so that we are constantly reminded of our learning

An Open Shop Approach in Approximating Optimal Data Transmission Duration in ...cscpconf
In the past decade Optical WDM Networks (Wavelength Division Multiplexing) are being used
quite often and especially as far as broadband applications are concerned. Message packets
transmitted through such networks can be interrupted using time slots in order to maximize
network usage and minimize the time required for all messages to reach their destination.
However, preempting a packet will result in time cost. The problem of scheduling message
packets through such a network is referred to as PBS and is known to be NP-Hard. In this paper
we have reduced PBS to Open Shop Scheduling and designed variations of polynomially
solvable instances of Open Shop to approximate PBS. We have combined these variations and
called the induced algorithm HSA (Hybridic Scheduling Algorithm). We ran experiments to
establish the efficiency of HSA and found that in all datasets used it produces schedules very
close to the optimal. To further establish HSA’s efficiency we ran tests to compare it to SGA,
another algorithm which when tested in the past has yielded excellent results.

Seam Carving Approach for Multirate Processing of Digital ImagesIJLT EMAS
This paper presents a new approach called S eam Carving for multirate signal processing of digital images. Increasing and decreasing the sizes of digital images are common place in day-today image processing. These methods involve long procedures and sometimes consume more time for getting implemented. Whereas, using the S eam Carving method eradicates the excess time involved in upsampling and downsampling a digital image considerably as this method is straightforward and simple to implement. This method comes in handy when we are dealing with large medical images and remotely sensed images. This technique is applied on standard images and its performance is analyzed. The entire work was implemented using Matlab R2017a software package.
Quality Measurements of Lossy Image Steganography Based on H-AMBTC Technique ...AM Publications,India
Steganography is a type of image information concealing technique which hides a secret message in a different media such as image, video and audio etc, called cover file. The main idea of steganography is to provide security to private or public data. In this paper we combined among Hadamard transformation and Absolute Moment Block Truncation Coding to make a new concept called (H-AMBTC), this concept used for compressing the cover file and conceal the secret data into the cover file. The H-AMBTC compression is not only image compression, but it is more than the AMBTC technique as only half of the number of pixels in the binary converted image are transmitted. In this paper, the comparison process of the H-AMBTC technique is done for 2x2, 4x4, 8x8 and 16x16 block sizes. H-AMBTC is a lossy technique as the cover image and the secret image can be recovered completely.
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
