In computer vision, blob detection methods are aimed at detecting regions in a digital image that differ in properties, such as brightness or color, compared to surrounding regions. Informally, a blob is a region of an image in which some properties are constant or approximately constant; all the points in a blob can be considered in some sense to be similar to each other. The most common method for blob detection is convolution.
Spot detection device, spot detection method, and display device
A spot detection device, a spot detection method, and a display device are provided. The spot detection device includes an imager and a spot detector, in which: the imager is configured to capture a display panel displaying a first image of a first gray scale and a second image of a second gray scale different from the first gray scale, and generate image data; and the spot detector is configured to receive the image data from the imager to detect a spot. The image data includes first image data obtained by capturing the first image, second image data obtained by capturing the second image, and a plurality of third image data obtained by capturing a portion of the first image.
