Watermarking based on DWT and SVD Algorithmin Medical Image

Medical images and accompanying reports have requirement of protecting the privacy of patient. The paper deals with the use of watermarking technique to increase the security of medical images and preserve patient?s privacy.The operation of embedding and extraction of watermark are done by using different watermarking algorithmsi.e Discrete Wavelet Transform, Singular Value Decomposition. Watermark is a normal image to be generated every time and which is to be embedded inside medical images. Then the quality of watermarked images which is obtained after embedding the watermark is to be accessed by calculating Peak Signal to Noise Ratio (between original and watermarked image) and Normalized Correlation (between the original watermark and extracted watermark)

Comparative evaluation of root canal disinfection by conventional method and laser: An in vivo study

Objective: The aim of this study was to comparatively evaluate in vivo the disinfecting ability of conventional method and lasers in root canals.Materials and Methods: Study criteria included 60 single rooted teeth, which were indicated for root canal therapy followed to dental caries and trauma with intact crowns. Such selected patients were randomly divided into 2 groups, namely, GroupA(30 teeth) and Group B (30 teeth). All clinical procedures were carried out under strict aseptic precautions. The teeth in Group A were subjected to biomechanical preparation followed by the treatment with the help of diode laser containing the gallium aluminum and arsenic, which emitted 980 nm wavelengths. The teeth in Group B were treated with routine method of biomechanical preparation along with irrigation using sodium hypochlorite and hydrogen peroxide. The microbiological samples were taken immediately after the access preparation and after the completion of the root canal disinfection and were sent for microbiological analysis.Results: The teeth in Group A showed presence of common strains of bacteria ranging from Streptococci, Staphylococci, Klebsiella, and Pseudomonas. Reduction in the growth of microorganisms was found for all types of microorganisms. Only 8 samples exhibited the growth after treatment with laser. Results of Group B also showed the presence of common strains of anaerobic and aerobic bacteria as shown in earlier studies, predominantly Staphylococcus, Streptococci, and Pseudomonas. Statistical analysis showed non‑significant P values for the microorganisms; however, only 3 samples showed the growth after treatment with conventional technique using sodium hypochlorite and hydrogen peroxide.Conclusion: Conventional method by using sodium hypochlorite and hydrogen peroxide as irrigating solutions is highly effective in disinfecting the root canal. Lasers when used can also reduce the bacterial load of the infected root canal.Key words: Diode laser, endodontics, root canal disinfectio

Study and Survey on Gesture Recognition Systems

In recent years, there has been a considerable amount of research in the Gesture Recognition domain, mainly owing to the technological advancements in Computer Vision. Various new applications have been conceptualised and developed in this field. This paper discusses the implementation of gesture recognition systems in multiple sectors such as gaming, healthcare, home appliances, industrial robots, and virtual reality. Different methodologies for capturing gestures are compared and contrasted throughout this survey. Various data sources and data acquisition techniques have been discussed. The role of gestures in sign language has been studied and existing approaches have been reviewed. Common challenges faced while building gesture recognition systems have also been explored.Comment: 6 pages, accepted at the ICCUBEA, IEEE 2023 conferenc

Inter thenar skin sparing carpal tunnel release- role of incisions and endoscope - A case report

Endoscope in plastic surgery has played a role, wherever minimal scarring is required. An attempt to decrease the length of scar is one of the priorities of a surgeon, as this brings down the chance of scarring, pain and associated morbidity, with decreased hospital stay. Hand is an organ with intricate anatomy and many vital structures are densely packed in hand. This makes the available space scarce for another instrument to add into the hand. Hence endoscopic intervention in hand is negligible. The margin of error also remains negligible in hand, as it would compromise on the function of hand, which is an absolute necessity. Aesthetic appearance of hand is not as important as function; nevertheless if possible, one should also consider giving an aesthetic scar with good function of hand and these criteria will be the goal for any hand surgeon. </jats:p

Intra operative challenges faced while performing palatoplasty in a case of mild PRS with isolated cleft palate- Importance of diagnosing subtle changes in pre-operative evaluation

Repairing cleft palate in a non-syndromic child is very challenging, given the size of oral cavity, a Pierre-robinsequence (PRS) makes matters worse on the operating table, as there is an added difficulty of micrognathia and relatively larger tongue. This paper is written with an objective of sharing our difficulties faced while operating in such a child, the technique used to cover the oral layer of soft palate, and to foresee such difficulties in the preoperative period in milder cases of Pierre robin sequence.</jats:p
