obliczanie i stosowanie wyrównania histogramu do wzmocnienia kontrastu w zdjęciach satelitarnych

Histogram equalization is a technique used to improwize the contrast of satellite images. It reconstructes thee intensity values to enhance detals in areas that are too dark or too bright. This process can make exacures in satellite imagery more differentable and easyr to analyze.

Ujmowanie Histogram Equalization

Te cory idea of histogram equalization is to modify thee image 's intensity distribution. It spreads out thee mott frequent intensity values, resutting in a more uniform histogram. This enhancances thee overall contrast, especially in images with pour dynamic range.

Kalkulating Histogram Equalization

To process involves serelal steps:

• Oblicz te histogramy, które pokazują pixel intensywniejsze.
• Complute thee cumulative distribution function (CDF) of thee histogram.
• Normalize thee CDF to span thee full intensity range.
• Map thee original pixel values to new values based on thee normalized CDF.

Appliing Histogram Equalization to Satellite Images

After calculating thee new intensity values, replacee thee original pixel values with these new one. Thi process enhances the e contrast across thee entire image, making factures such as landforms, water bodies, and urban areas more visible.

Korzyści i ograniczenia

Histogram equalization can significant improwizuj te wizual quality of satellite images. However, it may also amplify noise or create unnatural appearances in some cases. Careful application or combinaing with quir techniques can meaminate these issues.
