In the modern world, it is vital to ensure that appropriate encryption and decryption are used while sending data across the internet to avoid unwanted access. based on the visual cryptography system, a novel cryptographic scheme is suggested to secure color images. As inputs are a color image that needs to be protected and a binary image that serves as the encryption and decryption key. Three monochromatic images based on the YCb Cr color space are created from a secret color image that needs to be shared. Following the conversion of these monochromatic images into binary images, the binary images are then encrypted using binary key images, also known as share-l, to produce binary cipher images. Three half-tones of the secret color image and the binary key image are encrypted independently using the Exclusive OR technique. Share-2 is obtained by combining these binary pictures. After the shares have been encrypted, the binary images that have been retrieved are converted to inverted halftones and merged to create a hidden color image. This technique works better over a diffused channel for transmitting natural images. The OFDM technology is the foundation of this multi modal transmission. In wireless communications, OFDM as a multi-carrier transmission mechanism plays vital role. Due to its many benefits, including its fast data rate transmission, excellent reception quality, and capacity to counteract Inter-Symbol Interference (ISI), particularly in fading channels, the adoption of OFDM has grown significantly.A novel approach is put forward for progressive image transmission via Low Density Parity Check Coding (LDPC) on coded Orthogonal Frequency Division Multiplexing (OFDM) systems. In this technique, the Peak to Average Power Ratio (PAPR) of the OFDM signal is reduced and the performance of the OFDM systems is improved through the utilization of trigonometric transformations. It enhances progressive picture transmission's ability for error resilience and transm

signal filtering plays an important role in pre-processing procedures used in several application fields. In last years, several methods have been proposed by achieving good results. When large data are given in input, performance are likely to get worse. based on the Savitzky-Golay filter, we have developed, in this paper, a parallel implementation with engaging a multi-core architecture. Experiments and tests highlight the gain of performance in time terms.

We introduce the generative adversarial networks (GANs) into the application of the free-space laser communication, performing the laser-spot image restoration with the computer-vision method. After the training of our model is completed, the average Pearson correlation coefficient, average peak signal-to-noise ratio and mean-square-error of the generated restored laser spot image reach 0.964, 27.713dB and 0.003, respectively. According to the numerical results, the GAN method could effectively resist the interference of atmospheric turbulence, and accurately restore the amplitude distribution of the laser captured from the free-space channel.

With the increasing popularity of the internet of Things (IOT) and devices getting smarter, this research has presented an idea to reform the weather information for precision farming. In this study, the information of weather forecast was prepared for air quality control systems using the sensor of network systems to increase the quality of organic vegetable in Thailand under the condition of Thailand weather The prototype model was described by the devices of embedded systems, which is gotten from the temperature and humidity sensor. Therefore, if there is any data from the input sensor, the users are allowed to access and granted to use this system, then, the log data are transmitted by the internet to the designation website by using a Wi-Fi module (ESP8266). As a result, it can be used the machine learning algorithms for implementing of monitor controller, which is applied for analyzing and collecting data to air quality control in green house
