Hybrid Algorithm for Real-Time Sign Language Detection System

Oskar Krishna Shrestha S. P. Khatiwada Adarsha Ghimire Bibhuti Rajbhandari Ananthoju Vijay Kumar

This research paper suggests a machine learning-based system designed to interpret sign languages in real-time from a video feed to help deaf and hard of hearing individuals overcome communication barriers. Sign languages employ hand gestures, facial expressions, and body language to convey ideas and meaning visually. Unfortunately, individuals with hearing impairments face communication difficulties, limited access to information and services, and social isolation. The proposed system captures the subject's gestures using a camera, which are then processed using a TensorFlow object detection API that predicts based on a pre-trained machine learning model. The system's methodology incorporates supervised learning, Single Shot MultiBox Detector (SSD) object detection algorithm, and the luminosity method for converting colour images to grayscale. For dataset creation, hand gesture image samples were captured and labelled using open-source graphical annotation software LabelImg, and the model was trained. The system proposed achieved an average accuracy of 95% and has the potential to improve communication and reduce marginalization for deaf and hard of hearing individuals.

Delayed Transplanting of Aged Rice Seedlings Causes the Yield Reduction in Farmer's Field

Genomics and Applied Biology (2016)

Ujjawal Kumar Singh Kushwaha S. P. Khatiwada H. K. Upreti

Four year experiments were conducted to find out the causes of yield reduction of farmer’s field of Nepal from 2011 to 2014. Randomised complete block design with three replications were used to compare twelve rice genotypes with Khumal-4 as a standard check. One set of genotypes were transplanted in the last week of June and the other set was transplanted two weeks delayed as summer season rice. Results showed that rice different parameters like grain yield, plant height, panicle length, days to heading and days to maturity were found significant (p<0.05). Plant height, panicle length and fertile grain per plant were also found significant in early transplanted rice than delayed transplanted rice. Delayed transplanted aged rice seedlings took shorter days to flower and mature than early transplanted rice. On an average, 38.44% decrease in yield was found from early to delayed transplanted rice from 2011 to 2014. Similarly, grain yield of early transplanted rice was found higher than delayed transplanted rice in all the year. The reason could be that too early and too late transplanting could not fulfill the required temperature and photoperiod for rice crop. Late transplant of aged rice seedlings are severe to cold and effect plant growth and yield. Thus the yield reduction of farmer’s field can be minimised by transplanting rice in appropriate time with recommended package of practices.

Diallel Analysis of AI Toxicity Tolerance in Rice

International Rice Research Notes (2012)

S. P. Khatiwada D. Senadhira R. S. Zeigler A. L. Carpena Pedro González Fernández

We studied the genetics of Al toxicity tolerance using a full diallel set of crosses among seven parents with differing degrees of response to Al toxicity. The seven varieties were Moroberekan, IRAT104, and Azucena (tolerant); IR29 and IR43 (moderately tolerant); and IR45 and IR1552 (susceptible). Relative root length of 14-d-old seedlings, determined by growing seedlings in a normal nutrient solution and nutrient solution with 30 ppm Al, was used to characterize the tolerance of test materials. The experiment was conducted in a glasshouse at the IRRI Phytotron with 29/21 oC day/night temperature and 70% relative humidity. The experimental units consisted of 49 entries (7 × 7 diallel) in randomized complete block design with four replications. Eight seedlings were sampled for each entry in a replication.
