Health care images contain a variety of imaging information that has specific features, which can make it challenging to assess and decide on the methods necessitated to safeguard the highly classified visuals from unauthorized exposure during transmission in a communication channel. As a result, this proposed approach utilizes a variety of techniques that will enhance the quality of textual healthcare images, communicate information securely, and interpret textual data from healthcare visuals without difficulty. Natural interference, primarily on the receiver side, reduces text-based healthcare image contrast, and numerous artifacts and adjacent picture element values impede diagnosis. Therefore, at the transmission end, the suggested method uses morphological component analysis to improve the contrast of textual healthcare images. Subsequently, it masks this textual healthcare image behind the cover image using steganography, maintaining the secrecy of private information during transmission on the Internet of Medical Things (IoMT) network. After obtaining the stego-image, reverse steganography is used to separate the textual health care image from the cover image. Following that, pre-processing had been performed utilizing weighted guided image filters to ensure that a text-based health care image would not be altered when data had been sent through an IoMT. After that, the Gabor Transform (GT) and stroke width transform are then used to extract the features required for a weighted classification approach that distinguishes between healthcare images with and without text content. Employing the cultural emperor penguin optimization strategy strengthened the performance of the weighted naive Bayes classifier. Later, a hybrid convolutional neural network with enhanced cuckoo search optimization is utilized to detect textual information in healthcare images. A variety of indicators are utilized to evaluate each cover picture and text-based healthcare image. These are accuracy, precision, recall, sensitivity, specificity, structural similarity index, peak signal-to-noise ratio, number of bytes of embedded and recovered input health-care textual pictures, and mean square error. The findings show that the proposed strategy outperforms all of the existing approaches. The suggested method successfully retrieves content at the receiver end. However, a few characters may be misplaced or recovered many times due to weighted guided image filtration halo artifacts, which impair image quality and provide inaccurate textual data.
医疗保健图像包含具有特定特征的各种成像信息,这使得在通信渠道传输期间评估并确定保护高度机密视觉信息免遭未经授权曝光所需的方法具有挑战性。因此,本提议的方法利用各种技术,这些技术将提高文本医疗保健图像的质量、安全地传达信息并毫无困难地解读医疗保健视觉信息中的文本数据。自然干扰(主要在接收端)会降低基于文本的医疗保健图像的对比度,并且众多伪像和相邻像素值会妨碍诊断。因此,在传输端,所建议的方法使用形态成分分析来提高文本医疗保健图像的对比度。随后,它使用隐写术将此文本医疗保健图像隐藏在掩护图像之后,在医疗物联网(IoMT)网络上传输期间保持私人信息的保密性。获得隐秘图像后,使用逆隐写术将文本医疗保健图像与掩护图像分离。在此之后,利用加权引导图像滤波器进行预处理,以确保当数据通过IoMT发送时基于文本的医疗保健图像不会被改变。之后,使用伽柏变换(GT)和笔画宽度变换来提取加权分类方法所需的特征,该方法区分有和没有文本内容的医疗保健图像。采用文化帝企鹅优化策略增强了加权朴素贝叶斯分类器的性能。后来,利用具有增强布谷鸟搜索优化的混合卷积神经网络来检测医疗保健图像中的文本信息。使用各种指标来评估每个掩护图片和基于文本的医疗保健图像。这些指标包括准确率、精确率、召回率、灵敏度、特异性、结构相似性指数、峰值信噪比、嵌入和恢复的输入医疗保健文本图片的字节数以及均方误差。结果表明,所提议的策略优于所有现有方法。所建议的方法在接收端成功检索到内容。然而,由于加权引导图像滤波晕轮伪像,一些字符可能会错位或被多次恢复,这会损害图像质量并提供不准确的文本数据。
