- What is the relationship between resolution and pixel? A: Because the resolution is higher, the number of pixels per inch is more. B: Because the resolution is lower, the number of pixels per inch is less. C: Because the resolution is lower, pixels are smaller. D: Because the resolution is lower, pixels are greater.
- What is the reson of cameras capture images with the characteristic that not all the objects are in focus? A: The camera is not focusing properly B: Limited by the depth of field C: The shooting range is too wide D: There are too many objects in the depth of field
- Super pixels have emerged as a form of over-segmentation meant to provide clusters of perceptually similar pixels throughout an image, thus capturing the redundancy ____ in most natural images.
- According to the image standard, your product images must accurately represent the product for sale, be clearly visible, be professionally photographed, and be at most 10,000 pixels on the longest side, at least 1,000 pixels on the shortest side, and at least 500 pixels in height or width. ( )
- 1. For an image with 100 * 100 pixels, each pixel has 8-bits to express its gray scale.If the data volume of the compressed image is 40000 bits after Huffman coding , the compression ratio of the image is ( ). A: A. 4:1 B: B. 3:1 C: C. 1:2 D: D. 2:1
