Taiwan currently grapples with the intricate task of balancing its food supply and demand, resulting in the emergence of critical food surplus and waste issues. To address this pressing challenge, the government has turned to food donation initiatives led by public associations and private corporations to alleviate food waste concerns. Nevertheless, a significant obstacle remains in the form of the efficient and effective distribution of these fresh food donations from the supply side to the demand side. Therefore, this study aims to pioneer an innovative and optimized distribution model for fresh food donations employing TRIZ (Theory of Inventive Problem Solving) and grey relational analysis.

Through an in-depth analysis of questionnaire data gathered from the public, this research uncovers the most favored distribution model, namely, "Government-invited third-party logistics providers (3PLs) to voluntarily manage distribution services, alongside the provision of preferential subsidies or tax incentives." Building upon these findings, this study offers valuable recommendations for governmental agricultural authorities and other stakeholders within the fresh food donation supply chain, serving as a cornerstone for sustainable food management practices.

Enhancing visibility of nighttime images using wavelet de-composition with kekre's LUV color space

Pravin Pardhi, Sudeep Thepade — Sat, 01 Jun 2024 00:00:00 +0000

Contrast enhancement is a crucial preprocessing method for enhancing the efficiency of subsequent image processing and computer vision tasks. In the past, a lot of effort has been put into improving the visual scenes of pictures taken in low light. Images taken in poor illumination environments frequently reveal issues like color distortion, noise, low brightness, etc., that negatively impact the visual influence on human eyes. Therefore, an approach for improving poorly illuminated images based on wavelet transform is suggested to get around this problem. The input image is first transformed to Kekre's LUV color space, after which discrete wavelet transform (DWT) is applied to part each channel into low and high-frequency components. As the illumination is concentrated on the low-frequency image component, the Exposure-based Sub Image Histogram Equalization (ESIHE) technique is applied to enhance the image's lighting. Besides, limited adaptive histogram equalization (CLAHE) is imposed to control the over-enhancement of specific region's contrast. Modified L, U, and V components are recovered via the inverse discrete wavelet transform (IDWT), and the image is again converted into RGB space. This output is fused with a histogram equalized image using weighted fusion followed by a high boost filter to get the final enhanced output. Experimental outcomes are achieved to validate the efficacy and robustness of the suggested strategy using quality evaluators such as Entropy, NIQE, and BRISQUE rankings explored on ExDark, DPED, and LoLi datasets.

Prostate cancer (PCa) is currently the most frequently diagnosed cancer in men in industrialized nations and ranks as the second leading cause of male cancer-related deaths globally, early detection is crucial. Originating in the walnut-shaped gland beneath the bladder, PCa poses a significant risk when not identified in its early stages. The diagnostic process, requiring expertise from radiologists, pathologists, and physicians, is time-consuming and introduces variability, potentially leading to delayed or incorrect diagnoses. This underscores the need for efficient and reliable diagnostic tools in addressing the escalating challenge of PCa diagnosis.This study addresses the critical challenge of PCa diagnosis by employing a comprehensive approach involving feature selection methods and model performance evaluation. Utilizing a PCa dataset from Kaggle, consisting of 100 patient observations with eight independent features and a binary diagnosis result, the study explores the nuanced nature of feature relevance in PCa classification. Comparative analyses of Principal Component Analysis (PCA) and ReliefF feature selection methods reveal the limitations of PCA's emphasis on a dominant feature, while ReliefF, incorporating a distributed set of features, demonstrates improved model accuracy and stability. The Random Forest (RF) model, selected through meticulous parameter tuning, achieves an impressive 95% accuracy by leveraging a substantial number of estimators, limited tree depth, and balanced sample splitting. The findings underscore the crucial interplay between feature selection methods and model parameters in optimizing the accuracy and reliability of PCa classification models. Given the anticipated rise in PCa incidence, this research contributes valuable insights for enhancing diagnostic efficiency and addressing the challenges posed by traditional diagnostic procedures.

Within the fields of law enforcement and forensics applications, latent fingerprints have garnered a lot of interest from researchers. The need from the general public for these uses may be what propels biometrics research forward. Although a lot of work has gone into building techniques for latent fingerprint classification, there are still many difficult issues to solve low quality pictures, segmentation, noise, and intra class variations in that field. To overcome the above difficulties, proposed an Automated Latent Fingerprint Recognition framework in this research using strategies for latent fingerprint pre-processing, feature extraction, and matching. A candidate fingerprint's salient minutiae, which give each fingerprint its individuality and distinguish it from others, are first identified and described, followed by their relative placement in the candidate fingerprint and previously saved fingerprint templates. The experimental analyses using publicly accessible low-quality Latent partial fingerprints was taken from MSU PrintsGAN datasets show that the proposed framework achieves an average equal error rate (EER) value of 0.254 and TAR@FAR achieves 91.43 which is contrasted to various existing approaches.
