An Overview to Enhance Visual Cryptography Techniques
Abstract: A unique type of cryptographic method called "visual cryptography" allows for decryption to be carried out using only the human eye. Generally speaking, for some crucial security, in modern society, processing and protecting information from attacks is becoming a very important aspect for people. Researchers are developing new ways to protect information from unwanted intrusion. Numerous encryption methods have been discovered, with many more yet to be discovered. Visual ciphers …

Spectral Signatures to Achieve Accuracy
Abstract: AbstractSignature of spectrum is data convert appearances those to make for least accuracy variation by generalization and extension in place of expansion. Pixel form has subjected to change from multi-spectra issued to hyperspectral formation after issue of spectroscopic forms. Spectral signatures perform have scaled to measure from agronomy to metallurgical element detecting prosecution. Optimism appeared in species differentiation between coconut and palm oil plantation. Updating forms from spectroscopic hyper-spectra have …

Non-Contact Quantification of Swelling-Induced Deformation in Polymer Hydrogels Using Image Analysis
Abstract: Swelling of polymer hydrogels governs transport, mechanics, and functional performance in biomedical systems, yet it is often reported using bulk ratios that conceal spatially heterogeneous deformation and boundary-driven instabilities. This study presents a non-contact image-analysis framework to quantify swelling-induced deformation by tracking shape and boundary evolution from time-lapse imaging. The approach segments the hydrogel region, extracts a sub-pixel refined contour, and computes boundary displacement descriptors including mean and upper-percentile normal …
