Medical images are obtained from different optical scanners and devices to provide in-body diagnosis and detection. Such scanned/acquired images are tampered with/ distorted by the unnecessary noise present in the pixel levels. A Trans-Pixelate Denoising Scheme (TPDS) is implemented to denoise these pictures to enhance the diagnosis's precision. This scheme is specific for CT images with high noise between pixelated and non-pixelated boundaries. Therefore, the boundary detected from an input CT image is suggested for a trans-pixel substitution using a two-layer neural network. The first layer is responsible for verifying the substitution-based diagnosis accuracy, and the second is identifying trans-pixels that improve accuracy. The outcome of the neural network is used to train the noisy inputs under either of the conditions to improve the diagnosis accuracy. The Proposed TPDS improves diagnosis accuracy, precision, and pixel detection by 7.3%, 8.14%, and 13.05% under different trans-pixel rates/boundaries. Under the same variant, this scheme reduces error and detection time by 11.15% and 9.03%, respectively.
医学图像是从不同的光学扫描仪和设备中获取的,用于提供体内诊断和检测。此类扫描/获取的图像会受到像素级存在的不必要噪声的干扰/扭曲。实施了一种跨像素去噪方案(TPDS)来对这些图片进行去噪,以提高诊断的精度。该方案专门针对像素化和非像素化边界之间存在高噪声的CT图像。因此,建议使用两层神经网络对从输入CT图像中检测到的边界进行跨像素替换。第一层负责验证基于替换的诊断准确性,第二层负责识别提高准确性的跨像素。神经网络的结果用于在任一条件下训练噪声输入,以提高诊断准确性。所提出的TPDS在不同的跨像素率/边界下,将诊断准确性、精度和像素检测分别提高了7.3%、8.14%和13.05%。在相同变体下,该方案分别将误差和检测时间减少了11.15%和9.03%。
