Embodiment Construction

[0054] The technical solution of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0055] This embodiment is based on figure 1 The strawberry image to be segmented, the specific implementation steps are as follows:

[0056] Step 1, using a strawberry image RI collected by a digital image sensor such as figure 1 Shown, then the strawberry image RI that gathers is transformed into the strawberry image MI of YCrCb color space;

[0057] Step 2, extract the Cb color component value of each pixel in the strawberry image MI as clustering data;

[0058] Step 3, the user initializes parameters, and the initialization parameters include the number of segmentation categories D=2, the size of the harmony library Popsize=50, the learning rate of the memory library HMCR=0.96, the pitch perturbation rate PAR=0.65, and the maximum number of evaluation times MAX_FEs=200;

[0059] Step 4, the curren...

Abstract

The invention discloses a strawberry image segmentation method base on an integration strategy harmony searching algorithm. The tone disturbance operation of the harmony searching algorithm is integrated with three kinds of tone disturbance strategies; and thus advantage complementation of the three kinds of tone disturbance strategies are utilized fully. During the searching process, a tone disturbance strategy suitable for a current evolution state is selected adaptively according to feedback information of an adaptive value. In addition, the local searching operation is executed by using mean value information of a harmony base, so that the strawberry image segmentation is accelerated. Therefore, the segmentation speed of the strawberry image is increased and the segmentation precision is improved.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to a strawberry image segmentation method based on an integrated strategy harmony search algorithm. Background technique [0002] Strawberry is a kind of fruit rich in vitamin C and rich in nutrition, which is deeply loved by the masses of the people. Large-scale planting of strawberries is a very economical industry. In order to realize the large-scale planting of strawberries, it is necessary to realize the automation and intelligence of strawberry planting. Machine vision is the key technology for automation and intelligence in the strawberry production process. For example, the realization of strawberry intelligent picking robot and strawberry quality automatic sorting system needs to be based on machine vision. [0003] Strawberry image segmentation is one of the basic technologies of strawberry machine vision. The segmentation of strawberry images can be transformed...
