You can try this out if you have Matlab (or convert it into another language like C or Python if you don’t). The uncorrected 24-patch Colorchecker image shown on the right is used as the input to the Color Correction Matrix calculation. It was derived from a raw image, converted to ...
where \(H_{3 \times 3}\) here is a color homography color correction matrix, \(\alpha \) denotes an unknown scaling. Without loss of generality, let us interpret c as a homogeneous coordinate, i.e., assume its third component is 1. Then, rg chromaticities \(\underline{c}^\intercal...
The authors applied Gamma correction on the Luminance gain matrix obtained by converting from RGB to HSV channel. The resultant image is converted to Lab color space with an intermediate step conversion to RGB color. CLAHE is applied on the L channel, and the output is converted to RGB color...
Interphone variability arises due to the differences in software (ex. image processing algorithms like gamma correction, white balance, and color-space transformations) and hardware (ex. sensors, filters, and lenses) across different smartphones. This leads to different measured signals even when captu...
The first method uses white balance correction followed by a color space transformation. The second approach, applicable to images processed offline, is based on performing full color balance instead of white balance and requires the use of machine learning to predict the color balance matrix [7]....
4.2. Confusion Matrix In order to carry out the confusion matrix deployment with dataSetOriginal and dataSetFilter, this was done through the sk-learn library that was implemented in Python, as this library has a module to carry out the confusion matrix. DataSetOriginal.Table 6 shows the number...
The first method uses white balance correction followed by a color space transformation. The second approach, applicable to images processed offline, is based on performing full color balance instead of white balance and requires the use of machine learning to predict the color balance matrix [7]....
As shown in Figure 10a, after underwater image enhancement using AMSMC-UGAN, the RGB distribution of the output is close to that of the ground-truth reference image, which indicates that the AMSMC-UGAN method is effective in color correction for underwater images during underwater enhancement...
