Embodiment Construction

[0029] The general flowchart of the artificial target detection method of the present invention is as follows figure 1 As shown, a comprehensive feature consistency model is established first, and then the model is used to perform preliminary ROI detection on natural images, and finally it is post-processed using erosion and region labeling in mathematical morphology. The present invention will be further described in detail below in conjunction with model construction and examples.

[0030] 1. Introduction and parameter setting of logGabor filter bank

[0031] The logGabor filter surrounds a certain center frequency (r 0 , θ 0 ) of a Gaussian function. In the frequency domain, the logGabor filter consists of an even symmetric logGabor filter and an odd symmetric logGabor filter.

[0032] G ( r , θ ) = G ( ...

Abstract

The method comprises: creating a hybrid feature coherence model; using said model to detect the interested area in the nature image; using the corrosion and area-labeling in mathematical morphology to make post process for it.

Description

technical field [0001] The invention belongs to the technical field of image processing and pattern recognition, and in particular relates to a method for detecting artificial objects of interest in natural images. Background technique [0002] Object detection has a wide range of applications in both military and civilian applications. In modern warfare, all kinds of high-precision weapons must have a reliable automatic identification system to play a role, and target identification detection is one of the key technologies. In the civilian field, such as the judgment of diseased cells in medicine, the forecast of forest fire danger, face recognition, fingerprint recognition, iris recognition in identification, cloth defect detection and raw cotton fiber sorting in the cotton textile industry, etc., Target feature analysis and detection technology are key technologies in related industries. [0003] At present, the methods of object detection mainly include methods based o...
