銳化/清除水下圖像/自動澄清圖‪片‬ 4+

此應用程序澄清水下和海底圖像。

■整體
水下的顏色可能很奇怪。
圖像將呈現藍綠色調，看起來不清晰。

此應用程序校正色調並使用算法使它們看起來更清晰。

■這個應用程序在內部做什麼

當你下降到水下時，紅色首先會消失，這會使圖像顯得更藍和更綠。
通過調整每個顏色通道，可以還原顏色，使圖像看起來更自然，對比度更高。該算法旨在自動執行此操作。



■算法
1. 計算圖像的平均顏色。
2. 將顏色色移到紅色通道，直到最小紅色平均值為 60。
3. 用新的紅色創建 RGB 直方圖。
4. 找到低閾值水平和高閾值水平。
5. 歸一化數組，使閾值水平等於 0，閾值高等於 255。

This application clarifies underwater and undersea images.

■Overall
Colors can be strange underwater.
The image will have a blue-green tint and will not look clear.

This application corrects the color tones and uses algorithms to make them appear clearer.

■What this app does internally

As you descent underwater The red color will disappear as the first thing which will make the image appear more blue and green.
By adjusting each color channel, the colors can be restored and make the image appear more natural with higher contrast. This algorithm aims at doing this automatically.



■The algorithm
1. Calculate the average color for image.
2. Hueshift the colors into the red channel until a minimum red average value of 60.
3. Create RGB histogram with new red color.
4. Find low threshold level and high threshold level.
5. Normalize array so threshold level is equal to 0 and threshold high is equal to 255.
