Image pre-processing techniques are used to improve the quality of an image before processing into an application. This uses a small neighborhood of a pixel in an input image to get a new brightness value in the output image. These preprocessing techniques are also called as filtration and ...

Most OCR solutions come with a built-in layout analysis. You can however go a step further and applyZonal OCRtechniques to define exactly the part of the image holding the text you want to extract. Open Source Tools You Can Use To Improve OCR Accuracy ...
For image segmentation the unseeded region growing (USRG) technique has been selected from a variety of known techniques. Evaluation of the results was based on empirically defined quality function used for segmentation results. Not every method of colour quantisation, carried out as preprocessing ...

Preprocessing techniques, such as noise reduction and normalization, enhance image quality and improve diagnostic accuracy in medical image analysis. Noise reduction removes unwanted artifacts, making subtle details in medical images clearer. Normalization standardizes pixel intensities, ensuring consistent image...

With the disclosed techniques, however, a training application uses machine learning techniques to generate one or more trained preprocessors that reduce reconstruction errors when preprocessing images represented in a luma-chroma color space. The reconstruction errors correlate to an end-to-end loss of...
To investigate the effect of preprocessing techniques including contrast enhancement and illumination correction on retinal image quality, a comparative study was carried out. We studied and implemented a few illumination correction and contrast enhancement techniques on color retinal images to find out the...
