In this paper, a two-stage multi-category recognition structure based on texture features is proposed. This method can solve the problem of the decline in recognition accuracy in the scene of lightweight training samples. Besides, the problem of recognition effect different in the same recognition structure caused by the unsteady iris can also be solved. In this paper’s structure, digitized values of the edge shape in the iris texture of the image are set as the texture trend feature, while the differences between the gray values of the image obtained by convolution are set as the grayscale difference feature. Furthermore, the texture trend feature is used in the first-stage recognition. The template category that does not match the tested iris is the elimination category, and the remaining categories are uncertain categories. Whereas, in the second-stage recognition, uncertain categories are adopted to determine the iris recognition conclusion through the grayscale difference feature. Then, the experiment results using the JLU iris library show that the method in this paper can be highly efficient in multi-category heterogeneous iris recognition under lightweight training samples and unsteady state.

The article considers and reasons the ways and possibilities to create the highly efficient constructions of trenching excavators that dig trenches of the defined profile by means of using bucketless rotors as soil excavating implements together with design of the discharge assembly improved construction. Study objective: to create a bucketless highly efficient rotary implement of the trenching excavator with two-stage discharge. Study object: continuously operation earthmoving machines. Research technique – analytical-experimental. One of the most important problems for the machine-building industry of Ukraine is the efficiency improvement of machines created in the country. Solving of this problem is required due to necessity to perform the increasing amount of earthworks in building and construction works. The cheapest way to perform lengthy soil excavations is to excavate them with trenching excavators. Increasing of their productivity is the one of the main directions to improve the efficiency of the earthworks mechanization. Increasing the efficiency of trenching excavators is possible by means bucketless rotary implement usage and by improving of the rotary discharge process. The study justifies and proves the scientific hypothesis about the possibility to use the force of the soil flow header pressure create by the soil that is being transported from the excavation for the bucketless rotary implements discharge. This allows by means of two-stage discharge of the implement to ensure the full clean-up and to improve the productivity of the soil excavation. The study analytically justifies the requirements for the main construction parameters of the bucketless rotor. Based on the obtained results the technical proposal is created for highly efficient construction of the bucketless rotary implement of the trenching excavator with two-stage discharge.
