CH-2 – What is a Video – Part-6

The BMP (Bitmap) file format, standard for Windows, stores device-independent bitmap images. It can include compression but typically lacks animation support. Comprising structures like BITMAPFILEHEADER and BITMAPINFOHEADER, it specifies image dimensions, colors, and compression. The RGBQUAD array defines color components, while pixel data interpretation varies based on the BITMAPINFOHEADER. Notably, DIB rows are stored upside-down, with row byte counts adjusted to multiples of four. Key frames in videos are essential for defining movement sequences, serving as anchor points for animation. Feature extraction simplifies complex data analysis by constructing combinations of variables, reducing resource requirements while maintaining accuracy.
