ABSTRACT: In recent years, the application of Fourier infrared spectroscopy has become increasingly widespread. However, there is still room for improvement in its qualitative analysis for substance identification. Therefore, this paper proposes an infrared spectroscopy qualitative analysis method based on the Empirical Mode Decomposition (EMD) algorithm. The EMD algorithm is used to denoise the data, cubic spline interpolation is applied for baseline correction, and the.....

ABSTRACT:People are interested in approximate computing to make low-power, high-performance computers, which is in response to the growing need for computers that use less energy [2, 3]. A lot of different tasks need multipliers, like machine learning, image processing, and digital signal processing (DSP) [6, 8]. This work introduces an innovative approximation multiplier that optimises power efficiency and accuracy through the integration of higher-order compressors [9, 10]. These compressors reduce the amount of space needed, the amount of power used, and the time it takes to process data while keeping the required level of accuracy [5, 7]. To improve efficiency, we substitute the......

ABSTRACT:Super-resolution (SR) become the most important task in image processing because of requirement of high quality of images. It becomes popular in technology like computer vision and pattern recognition. In Single Image Super-resolution (SR) uses the sequences of single low resolution (LR) images from high resolution (HR) to improve the quality of image. The SR is an image processing problem which aims to generate a high resolution (HR) image from low resolution input image. The SR is difficult because of the missing information in the given LR image.......

ABSTRACT:The need for high capacity long haul telecommunication system to carry huge traffic demands in recent times has lead to the use of optic fiber communication system because of its high capacity carrying advantage over wireless systems. But optic fiber signals suffer some signal impairment issues such as nonlinearity which tends to degrade its transmission performance. This paper proposed the use of adaptive optical equalizer to mitigate such impairments. To achieve that, a simulink model of the system was first developed for simulation experiments. Then......
