Problems solved by technology

The target to be separated, such as using the marine remote sensing image generated by Synthetic Aperture Radar (SAR, Synthetic Aperture Radar) to detect seabed terrain information, has two-dimensional characteristics no matter in terms of shape or correlation with surrounding information. Therefore, only using one-dimensional separation method to process two-dimensional non-stationary electromagnetic echo image data is obviously unable to meet the requirements, and the accuracy of the processing results is poor, often mixed with information of other characteristic scales

Embodiment 1

[0089] Embodiment 1, as shown in FIGS. 1 to 6-3 , the method for separating two-dimensional image data with multi-scale information is applied to the processing of SAR images for detecting seabed terrain information.

[0090] As shown in Figure 6-1, the original two-dimensional ocean SAR image is actually generated, which contains a variety of characteristic scale information, from which it is necessary to gradually separate the wave motion, current field, wind field, mean field and circulation field, etc. Separate single-scale layers.

[0091] First, separate the information layer that reflects the wave motion from the original SAR two-dimensional image, as shown in Figure 5, the operation steps of the separation method are:

[0092] The first step is to acquire the above-mentioned SAR two-dimensional image data, that is, to obtain the two-dimensional original data in the image.

[0093] The second step is to determine the extremum points in the original data of the above-me...

Abstract

A method for separating two - dimensional image data with multiple - dimension information includes two points as that separating and separated out images are all two - dimensional images and multiple - dimension information is contained in the image. The aim of the method is to separate one two - dimensional image to be a numbers of dimension separated '' image - layer'' as each ''image -layer'' only containing single dimension of target object information.

Description

technical field [0001] The invention relates to a data separation method for two-dimensional images formed by electromagnetic echoes, in particular to separate two-dimensional image data according to each scale standard. Background technique [0002] In the fields of marine survey and geological exploration, electromagnetic echo remote sensing technology is widely used at present. Electromagnetic echo imaging uses the unique electromagnetic radiation characteristics of the object. When the photoelectric or microwave detector receives the electromagnetic wave emitted, reflected or stimulated by the object, it can convert the electromagnetic radiation into an electrical signal, and the electrical signal can be converted into image. The electromagnetic wave generated by each part of the detection object (called a pixel) directly reflects the physical characteristics of the detection object, and the converted signal is reflected on the two-dimensional image. The intensity and d...
