A point contact/Coulomb coupling technique is generally used for visualizing the ultrasonic waves in Lead Zirconate Titanate (PZT) ceramics. The contact and delta pulse excitation produce a broadband frequency spectrum wide directional wave vector. In ultrasonic, signal corrupted with several types of noises such as speckle, Gaussian, Poisson, salt pepper noise. Consequently, resolution quality images are degraded. reliability health assessment any civil or mechanical structures highly...

The performance of large language models (LLMs) on existing reasoning benchmarks has significantly improved over the past years. In response, we present JEEBench, a considerably more challenging benchmark dataset for evaluating problem solving abilities LLMs. We curate 515 pre-engineering mathematics, physics and chemistry problems from highly competitive IIT JEE-Advanced exam. Long-horizon top deep in-domain knowledge is essential in this benchmark. Our evaluation various open-source...

Retinal fundus images play an essential role in the diagnosis of retina-related diseases and hence, their quality enhancement is for doctors to make a reliable clinical diagnosis. This paper presents advanced retinal image method by employing efficiently modified biologically inspired levy-flight firefly optimizer association with novel optimally weighted piecewise gamma corrected energy redistributed dominant orientation based texture histogram equalization framework imparting overall...

In this paper, an efficient statistical approach employing a highly adaptive gamma correction based on adaptively clipped and locally equalized histogram using mean-median pair, is presented for the enhancement of low contrast dark images without losing their intrinsic features. For purpose, linearly stretched intensity range segmentation, first median mean distribution sub-histograms are derived local equalization after optimal clipping. Later on, non-linear transformational mapping has...

In this paper, the gamma corrected adaptive knee transformation, proposed by Monobe et al. is reviewed and improved exploiting two-dimensional single level Beta wavelet filter for subband decomposition of low contrast satellite images. For purpose, input image initially decomposed into its images such as low-low (LL), low-high (LH), high-low (HL), high-high (HH)). Then, LL-band coefficients are transformed to obtain enhanced applying transformation. Finally, it combined with rest subbands...

In this paper, a highly adaptive swarm intelligence inspired optimally gamma corrected intensity coverage maximization approach has been proposed for quality enhancement of dark and low contrast remotely sensed images. Various image techniques have till date, but in case images, most them are suffering from saturation effects higher regions along with information loss due to it; hence, not appreciated very well. Also, the available unable utilize entire allowable range, fully fruitfully....

The recently proposed DNS-over-HTTPS (DoH) protocol is becoming increasingly popular in addressing the privacy concerns of exchanging plain-text DNS messages over potentially malicious transit networks (e.g., mass surveillance at ISPs). By employing HTTPS to encrypt communications, DoH traffic inherently becomes indistinguishable from regular encrypted Web traffic, rendering active disruption downgrading DNS) by extremely hard. In this work, we investigate whether indeed traffic. To end,...

A recent innovation in the Indian banking structure has been formation of a new institution—small finance banks (SFBs). These are expected to penetrate into financial inclusion by providing basic and credit services with differentiated model larger population. In this context SFBs have multiple challenges coming out new, business model. The include building low cost liability portfolio, technology management, balancing regulatory compliances. This paper also presents top mind views three...

In this paper, an efficient statistical approach, employing a highly adaptive gamma correction based on regionally distributed and independently equalized histograms for all regions followed by contextual clipping, is presented overall enhancement of low contrast dark images keeping their intrinsic features preserved. For purpose, input image uniformly subdivided into several non-overlapping equal sized regions. A good estimation has been achieved classifying these three groups namely corner...

Overall enhancement for poorly illuminated satellite images (remote sensing images) and similar dark (from other domain) is always a very challenging task where information inherited in dense manner. In general, conventional intensity-based approaches usually suffered with insufficient colorfulness as well saturation artifacts, hence, never leads to desired overall such. This article presents novel gamma correction strategy, the value-set itself has been derived from optimally compressed...

Fractional-order integration (FOI) and its beauty of optimally ordered adaptive filtering for image quality enhancement are latently too valuable to be casually dismissed. With this motivation, a new Riemann-Liouville fractional-order calculus-based spatial-masking methodology is proposed in paper association with counterbalanced piecewise gamma correction (PGC). A generalized FOI-based mask also suggested. This negatively augmented the original harvesting texture-based benefits. PGC just...

In this paper, an efficient and relatively fast approach for satellite image enhancement is proposed. This technique based on auto-knee transfer function with suitable gamma correction using slantlet transform two-scale decomposed image. Dark or low contrast, big-data (or large sized) multispectral images can be easily enhanced by proper tuning the value of gamma-parameter transform. Here, sub-band decomposition achieved employing single-level filter-bank, which just equivalent to...
