 ## Histogram Detector
 
-The scene change detection algorithm uses histograms of the Y channel in the YCbCr color space to detect scene changes, which helps mitigate issues caused by lighting variations. Each frame of the video is converted from its original color space to the YCbCr color space.The Y channel, which represents luminance, is extracted from the YCbCr color space. This helps in focusing on intensity variations rather than color variations. A histogram of the Y channel is computed using the specified number of bins (--bins/-b). The histogram is normalized to ensure that it can be consistently compared with histograms from other frames. The normalized histogram of the current frame is compared with the normalized histogram of the previous frame using the correlation method (cv2.HISTCMP_CORREL). A scene change is detected if the correlation between the histograms of consecutive frames is below the specified threshold (--threshold/-t). This indicates a significant change in luminance, suggesting a scene change.

 ### GUI
 
-A graphical user interface will be crucial for making PySceneDetect approchable by a wider audience.  There have been several suggested designs, but nothing concrete has been developed yet.  Any proposed solution for the GUI should work across Windows, Linux, and OSX.
