By evaporating soil stylebook in vacuum and shooting the stylebook by electron microscope then, finally, some soil microphotographs are got.

Approach to the algorithm of gray image edge detection in different illuminati on conditions;

A gray image representation algorithm by using the direct triangle and rectangle non-symmetry and anti-packing model;

The Conversion Program Design Of Color Images And Gray Image;

The gray-level image of solid woven fabrics is captured by a color scanner and converted into digital files,then enhanced images are obtained by a gray-level morphological operation.

With visual frequency sensitivity,gray scale enhancement,Just Noticeable Distortion(JND) on gray-level image,this arithmetic selects DCT-block to compress watermarking image and make automorphic disorder,then embeds watermarking.

Research on edge detection of noise gray-scale image based on multi-structuring elements;

And based on the rule of edge detection of gray-scale images,this paper also proposes the range of parameters in template of CNN for detecting edges of gray-scale images.

A nonlinear filtering algorithm was presented to remove salt and pepper noise from gray-scale image while preserving details.

To better the visual effect by turning grey images into colored images, the colorization processing of image is to .

By turning grey images into colored images,the visual effect and recognition capability can be strengthened.

According to the disadvantages of Reinhard colour transfer algorithm and Welsh grey image-colorizing algorithm,this paper proposes a grey image colorizing algorithm based on pels space relativity.
