The banana diseases directly affected quality and yield, so a detection method for leaf based on image processing is proposed. Firstly, the color segmentation used to remove green background such as healthy leaves, weed from original disease collected by smart phone. And segmented converted V component gray of YUV space then Ostu which uses minium intra-cluster or maximum inter-cluster variance segment image, area threshold are non soil, dead grass, thus extracting complete regions. Next,...
In view of the complexity original banana leaf disease image collected by smart phone, an segmentation method is proposed. It combines with color segmentation, Ostu which uses minium intra-cluster or maximum inter-cluster gray variance to segment image, and area threshold method. Firstly, used remove green background according characteristics images. Secondly, converting RGB YUV space after in U component segmented non background. Area eliminate noise. Finally, method, processed "AND"...
Due to the detrimental impact of fog on image quality, dehazing maritime images is essential for applications such as safe navigation, surveillance, environmental monitoring, and marine research. Traditional techniques, which are dependent presupposed conditions, often fail perform effectively, particularly when processing sky regions within in these conditions not met. This study proposes an adaptive area segmentation dark channel prior method. effectively addresses challenges associated...
Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a common disorder caused by upper airway blockage, leading to oxygen deprivation and disrupted sleep. Traditional diagnosis using polysomnography (PSG) expensive, time-consuming, uncomfortable. Existing deep learning methods facial image analysis lack accuracy due poor feature capture limited sample sizes. To address this, we propose multimodal dual encoder model that integrates visual language inputs for automated OSAHS diagnosis. The...
In this paper, first the structure and composition of a new linear actuator with Soft Magnetic Composite material is presented. Next we study simulation model actuator. By pole-placement design, state-space full-state feedback control obtained. The result given, compared experiment. results show that two are basically same.
Anthurium is known as a famous and precious cut flower in the world, but its growth ornamental effect easily affected by environmental conditions such temperature, humidity light intensity. An environment parameter monitoring system based on wireless sensor network proposed to let managers understand status of anthurium at any time, take effective measures improve environment. The uses nodes acquire data air temperature humidity, intensity soil sink node collect from through network, send PC...
Considering the importance of real-time monitoring tropical flower environment parameters, paper designs a wireless system based on MSP430F149 for growing parameters. The proposed uses sensor nodes to obtain data temperature, humidity and light intensity, sink node collect from through network, center process downloaded RS232 serial port. hardware platform is composed processor, AM2306 NHZD10AI sensors used adopt intensity data, an nRF905 RF chip receive send data. software, operated in IAR...
In this paper, first we present the structure and fabrication of a new linear actuator made Soft Magnetic Composite material with mechanical springs. Next study simulation model actuator, result is given compared experimental result. The calculated corresponds measured one well.
