I want to compare 2 images, where the first image is stored in a database and the second image is from a live video stream via a webcam. Is it possible to determine whether there are some differences between the images, or whether they are identical?

I want the image comparison to be pixel by pixel. If a pixel by pixel comparison is hard, or even impossible, could you suggest a better way of doing this?

Web カメラの画像にノイズがあるため、単純なピクセルごとの比較はうまく機能しない可能性があります。

ピーク信号対雑音比 (PSNR)や構造的類似性 (SSIM)などの類似性測定が必要です。
