The data range of the input image (distance between minimum and maximum possible values). We have proposed a pixel-wise classification technique to accurately identify the area of an image containing relevant text, to feed them to a conventional OCR engine in the hopes of improving the quality of the output. The main anthropometric parameters are body mass, height, and head circumference. However, the ability of MSE (and PSNR) to capture perceptually relevant differences, such as high texture detail, is very limited as they are dened based on pixel-wise image differences [59, 57, 25]. matlabMSEPSNRMAESSIM Ternence06: K1K2 This non-contact method can prevent the transmission of infectious diseases, especially during the COVID-19 pandemic. X; Y; . Extending these factors can improve the delivery of the messages and, consequently, network performance; however, due to the limited network resources, it increases the cost and appends the network overhead.

Open Access free for readers, with article processing charges (APC) paid by authors or their institutions. The difference with respect to other techniques mentioned previously such as MSE or PSNR is that these approaches estimate absolute errors; on the other hand, SSIM is a perception-based model that considers image degradation as perceived change in structural information, while also incorporating important perceptual To this end, the correct perception of driving conditions is imperative for a driver to react accordingly to a given driving situation. No special Image quality assessment: from error visibility to structural similarity[J]. In the final section, we discuss future directions, including the sniffing attack mitigation framework in IoMT devices operating under a machine implantable communication system (MICS).
