Due to the advancement of multimedia and its requirement of communication over the network, video compression has received much attention among the researchers. One of the popular video codings is scalable video coding, referred to as H.264/AVC standard. The major drawback in the H.264 is that it performs the exhaustive search over the interlayer prediction to gain the best rate-distortion performance. To reduce the computation overhead due to exhaustive search on mode prediction process, this paper presents a new technique for inter prediction mode selection based on the fuzzy holoentropy. This proposed scheme utilizes the pixel values and probabilistic distribution of pixel symbols to decide the mode. The adaptive mode selection is introduced here by analyzing the pixel values of the current block to be coded with those of a motion compensated reference block using fuzzy holoentropy. The adaptively selected mode decision can reduce the computation time without affecting the visual quality of frames. Experimentation of the proposed scheme is evaluated by utilizing five videos, and from the analysis, it is evident that proposed scheme has overall high performance with values of 41.367 dB and 0.992 for PSNR and SSIM respectively.

Background: Laparoscopic cholecystectomy has become the mainstay of treatment for gallstone disease cases due to its lower morbidity and pain compared to open techniques. Unfortunately, the use of carbon dioxide to insufflate the abdomen is the main contributor to post-operative shoulder pain. Aims and Objectives: The aim of the study was to evaluate the effectiveness of retaining the epigastric port trocar in position until rest all ports closed after completion of lap cholecystectomy in decreasing the post-operative shoulder pain. Materials and Methods: A prospective, randomized, and clinical trial was done in AIIMS hospital, Bhubaneswar, on 102 patients who have undergone laparoscopic cholecystectomy. The patients were alternatively selected, one in the study group (52) and the other in the control group (50). For those patients in the study group, after the completion of the surgery, the epigastric port trocar is retained in position until the rest of all ports were closed. In the control group, all trocars were removed and port closure was done. The patients were evaluated for the next 24 h for post-operative shoulder pain. A numerical rating scale (NRS) was used to assess shoulder pain on patient arrival to the ward, at 4, 6, 12, and 24 h postoperatively. One hundred and two patients were included in the final data analysis. Results: NRS pain scores were significantly lower in the study group at 6, 12, and 24 h post-laparoscopic cholecystectomy compared to the control group with no additional requirement of IV analgesics. Conclusion: Retaining the epigastric trocar in position is an easy way that is beneficial in reducing post-operative shoulder pain post laparoscopic cholecystectomy surgery.
