Abstract: A gas leakage detection method is provided. The method includes the followings steps. Receive an infrared video. Capture a first image and a second image from the infrared video, wherein the first image and the second image are consecutive image frames in order. Calculate a difference between the first image and the second image to generate a first difference image. Filter the first difference image with a filtering criterion to generate a first filtered image. Transform the first filtered image with a transfer function to generate a first detail image, wherein the absolute value of pixel value in the first detail image is greater than or equal to the absolute value of corresponding pixel value in the first filtered image. Superimpose the first detail image and the first image to generate a gas leakage enhanced image.
