Affected by the hardware conditions and environment of imaging, images generally have serious noise. The presence of noise diminishes the image quality and compromises its effectiveness in real-world applications. Therefore, in real-world applications, reducing image noise and improving image quality are essential. Although current denoising algorithms can somewhat reduce noise, the process of noise removal may result in the loss of intricate details and adversely impact the overall image quality. Hence, to enhance the effectiveness of image denoising while preserving the intricate details of the image, this article presents a multi-scale feature learning convolutional neural network denoising algorithm (MSFLNet), which consists of three feature learning (FL) modules, a reconstruction generation module (RG), and a residual connection. The three FL modules help the algorithm learn the feature information of the image and improve the efficiency of denoising. The residual connection moves the shallow information that the model has learned to the deep layer, and RG helps the algorithm in image reconstruction and creation. Finally, our research indicates that our denoising method is effective.
受成像硬件条件和环境的影响,图像通常存在严重噪声。噪声的存在会降低图像质量,并损害其在实际应用中的有效性。因此,在实际应用中,减少图像噪声和提高图像质量至关重要。尽管当前的去噪算法可以在一定程度上降低噪声,但去噪过程可能会导致复杂细节的丢失,并对整体图像质量产生不利影响。因此,为了在保留图像复杂细节的同时提高图像去噪的有效性,本文提出了一种多尺度特征学习卷积神经网络去噪算法(MSFLNet),该算法由三个特征学习(FL)模块、一个重建生成模块(RG)和一个残差连接组成。三个FL模块帮助算法学习图像的特征信息并提高去噪效率。残差连接将模型学到的浅层信息转移到深层,RG帮助算法进行图像重建和生成。最后,我们的研究表明我们的去噪方法是有效的。
