研究目的
To enhance digital microscopic pneumonia bacteria images using image processing methods, specifically evaluating median filter, wiener filter, single scale retinex, and multiscale retinex for grayscale and color image enhancement.
研究成果
Median filter is superior for grayscale image enhancement, and multiscale retinex is superior for color image enhancement of pneumonia bacteria images, as indicated by higher PSNR values. This provides a basis for improving image quality in medical diagnostics.
研究不足
The study is limited to specific filters and retinex methods; it may not generalize to other image types or enhancement techniques. Future work could involve developing more detailed enhancement schemes.
1：Experimental Design and Method Selection:
The study employs image processing techniques including median filter and wiener filter for grayscale image enhancement, and single scale retinex (SSR) and multiscale retinex (MSR) for color image enhancement. Performance is evaluated using PSNR metrics.
2：Sample Selection and Data Sources:
Digital microscopic images of Pseudomonas aeruginosa bacteria are used, sourced from laboratory samples.
3：List of Experimental Equipment and Materials:
Digital microscope for image acquisition; computer for image processing; software for implementing filters and retinex algorithms.
4：Experimental Procedures and Operational Workflow:
Images are processed using median and wiener filters for grayscale enhancement, and SSR and MSR for color enhancement. PSNR is calculated to compare original and enhanced images.
5：Data Analysis Methods:
PSNR and MSE are computed to assess image quality, with higher PSNR indicating better enhancement.
