Its primary objective is to address the degradation of image quality caused by mixed impulsive noise during real-time image transmission and reception. Existing median filters often struggle to provide real-time image processing results that meet high standards in terms of both accuracy and speed. This approach effectively suppresses noise in real-time images while preserving essential edge details, which are crucial for the performance of real-time imaging systems. The algorithm introduces a novel technique of replacing noisy pixels with the processed central value within the image filtering window. This ensures fidelity to the original pixel, which is vital for applications such as image filter cores. To handle high noise densities in real-time systems, the methodology employs a scalable sorting approach for median filtering and an impulse detector, ensuring robust noise reduction without excessive computational complexity. The AI-enabled scalable median filter system achieves a significant reduction in dynamic power consumption, realizing an impressive 46% decrease in power consumption and an 82% reduction in area compared to the existing system. This is particularly beneficial for addressing resource and power-aware constraints in real-time systems.

Nevertheless, multi-port DC-DC converters have encountered challenges like bulky transformers and multiple switches, resulting in reduced reliability. To address these issues, this study presents super lift Luo and buck converter (SLBC) designed for the integration of PV and EV. The DC-DC converter presented in the work, integrated with SLBC, produces both step-up and step-down outputs from single input. The step-up output is achieved through the application of the super-lift method, enabling the elevation of voltage. This method allows for the generation of high-gain voltages using straightforward structures, eliminating the need for additional transformers or electric circuits for control and regulation. For fine tuning the duty cycle of the proposed converter, an efficient control scheme employing a cascaded structure of the TID (tilt integral derivative) with FOPID (fractional order proportional integral derivative with a filter), referred as the cascaded TID-FOPID controller is proposed. The tuning of the cascaded TID-FOPID controller parameters is accomplished using improved Harris Hawks optimization (IHHO). The analysis is carried out in the MATLAB platform and compared to various existing approaches. Analysed parameters include motor torque and speed, converter efficiency across duty cycles (0.1 to 0.6), frequency response, voltage gain comparative analysis among converters at a duty cycle of 0.6, voltage gain, voltage stress, and diode stress comparisons in the proposed converter.
