The majority of modern healthcare systems rely their diagnoses on data collected from the internet. The medical imaging and patient health records are transmitted over the network via the internet-enabled healthcare (E-health) applications. In practical medical applications, the primary problem is the security of medical images transmitted over the internet. For the purpose of embedding secret data on medical images without affecting important information, a trustworthy watermarking approach is required. We provide a unique watermarking approach in this research that embeds the watermark data in the medical image's Region of Non- Interest (RONI). The medical image is subjected to a contourlet transform, and RONI is determined using contourlet coefficients. In this work, we demonstrate the embedding and extraction process of medical image watermarking using Contourlet transform. Experiments are carried out on medical images such as MRI and CT images. The performance of the proposed scheme is analyzed using the metric PSNR. The proposed scheme provides an average PSNR value of 47.1604% for MRI images and 57.5452% of PSNR for CT images.

“…It is a highly practical field where we teach digital systems, using camera sensors to identify visual triggers and then subsequently automate tasks. The task might be as trivial as detecting road signs, as proposed by Danti and Kilkarni [1] or it can be highly specific like watermarking images as proposed by Yadav [2].…”

An Effective Technique for Determining Fish Freshness using Image Processing

This paper presents an efficient image processing based algorithm to determine the freshness of a fish. The determination is made after judging the condition of the eyes and the gills of the sample. The method is applicable for most edible fishes and can be easily reconfigured by changing the effect that the two determinants have on the final outcome. The novelty of the method lies in the ability of the algorithm to easily adapt to new samples which is a result of the universal applicability of the parameters selected. The method shows highly accurate results when compared to the ground truth.
