Equalize Selected Area

What is Selective Area Histogram Equalization

Selective area histogram equalization is an advanced image processing technique that applies contrast enhancement only to a specific region of an image while leaving the rest unchanged. This method is particularly useful when only part of an image suffers from poor contrast or when you want to enhance details in a specific area without affecting the overall image composition. It combines the benefits of histogram equalization with precise spatial control.

What is Online Selective Area Equalization Tool

An online selective area equalization tool allows you to apply histogram equalization to specific regions of your image using an intuitive crop selection interface. You can define the area to be enhanced by dragging and resizing a selection box, then apply contrast enhancement only to that region. This tool is perfect for enhancing specific subjects, improving visibility in shadowed areas, or correcting exposure issues in targeted regions without affecting the entire image.

How to Equalize Selected Areas

Upload your image using the file selector or drag and drop area. A red selection box will appear - drag and resize this box to define the area you want to enhance. The selection can be moved by clicking and dragging inside the box, and resized using the corner and edge handles. Once you've selected the desired area, the histogram equalization is automatically applied to enhance contrast within that region only. The rest of the image remains unchanged, preserving the original composition. Click 'Equalize Area' to finalize the enhancement, then download your selectively enhanced image.
