“…Combining color stretching, histogram equalization, amplitude compression, and saturation maximization methods, some researchers used correction gamma values to achieve grayscale enhancement [2], [3], [4]. Combining galaxy swarm optimization and particle swarm optimization, researchers used the method of weighted features and Gaussian distribution to achieve adaptive histogram equalization and gamma correction [5], [6], [7], [8].…”

Due to the charge capture of color inks in chromatic electrowetting electronic paper, the contact angle hysteresis and inconsistent aperture ratio result in a narrower color gamut and reduced contrast of the display screen. To address the issue, we propose an adaptive color conversion and dynamic enhancement display algorithm based on the aperture ratio of the chromatic electrowetting. Combined with the change of the aperture ratio, the reasonable grayscale allocation is made for color space conversion. Furthermore, considering the average grayscale values of each color, we design a method of the dynamic contrast enhancement and histogram equalization based on aperture ratio segmentation. In addition, considering the problem of grayscale loss in reflective displays, we propose an adaptive domain error diffusion algorithm with saturation enhancement to compensate for color loss. The experiments demonstrate that the images processed by our algorithm have shown certain improvements in evaluation indicators compared to images processed by other methods. Most significant of all, it has better visual display effect on chromatic electrowetting electronic paper, displaying more details.INDEX TERMS Electrowetting on dielectric (EWOD), color conversion, image enhancement, image quality optimization.

“…There are many reasons for its failure. For example, the temperature is too high, the fuel supply is insufficient, or a series of problems are caused by the aging of mechanical parts and components, such as serious wear of piston rings and rupture of cylinder heads, and some phenomena are caused by the failure of various components in the automobile system or other aspects due to some uncertain factors in the engine, Thus, the working performance and reliability of the whole machine are reduced [1][2].…”

The automobile engine is a high-speed vehicle. Its working principle and process are to generate gas through fuel burning, and then convert the chemical energy contained in the exhaust gas into heat energy. However, in reality, due to various reasons, serious wear and tear inside the engine and sharp reduction of mechanical strength have occurred. This paper mainly introduces a method based on particle swarm optimization algorithm to simplify the complex structure between various systems in the car and outside. The analysis shows that this method has the advantages of accuracy and reliability, and can effectively diagnose and predict it. The advantage of large workload and small space is very prominent. After that, this paper designs a fault diagnosis model of automobile engine based on particle swarm optimization algorithm, and tests the model. The test results show that the fault diagnosis time of this model is short, and the fault diagnosis accuracy is high, which can meet the user needs.
