Fine-grained image classification (FGIC) is a challenging task due to small visual differences among inter-subcategories, but large intra-class variations. In this paper, we propose a fusion approach to address FGIC by combining global texture with local patch-based information. The first pipeline extracts deep features from various fixed-size non-overlapping patches and encodes features by sequential modeling using the long short-term memory (LSTM). Another path computes image-level textures at multiple scales using the local binary patterns (LBP). The advantages of both streams are integrated to represent an efficient feature vector for classification. The method is tested on six datasets (e.g., human faces, food-dishes, etc.) using four backbone CNNs. Our method has attained better classification accuracy over existing methods with notable margins. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

An Opportunistic Network (OppNet), as opposed to a ubiquitous centralized network, relies on sporadic and opportunistic encounters between nodes to facilitate communication. The uncertainty about the node's nature presents challenges when nodes with malicious intents are present in the network. One category of malicious nodes includes blackhole nodes, which receive messages but drop them intentionally. In this paper, we introduce a novel trust function designed to detect blackhole nodes within the network. Our function has been widely tested and simulated to validate and increase the efficacy of transmission of messages in the network. We have performed a comparative analysis with various protocols (PROPHET, Epidemic and Spray And Wait) on several parameters such as Delivery Ratio, Overhead Ratio and Number of Messages dropped. The results demonstrate that our trust function is able to correctly detect and avoid blackhole nodes. We observed significant improvement in delivery ratio in Epidemic Routing (47%), Prophet (41%), and Spray And Wait Routing (17%) protocols when adjusting blackhole nodes while keeping the total network nodes constant. © 2023 IEEE.

Visually impaired individuals face difficulties in public transportation, especially in recognizing bus numbers. Though existing image captioning method can provide some bus scene information via voice broadcasting, precisely recognizing bus number while analyzing complex scenes remains challenges. To overcome this bottleneck, we propose a novel Text based Depth-aware image Captioning network (TDCnet) that facilitates a deeper understanding of the spatial relationships and geometric configurations of objects within bus scenes. Specially, we first carefully construct a new real-world dataset of bus scene integrated with bus number of LED strobe effect, to ensure generality and representations in practice. Then, we incorporate the depth information into the object and optical character recognition (OCR) feature for exploiting the spatial geometric relationships and capturing high-level semantic information. Finally, the experimental results demonstrate the necessity of constructing the Buscap dataset by comparing it with the public Textcap dataset. Besides, the comparison with other competing benchmark models verifies the effectiveness and practicability of the proposed TDCnet method. © 2024 Copyright held by the owner/author(s).

Unpredictable fruit and vegetable prices create significant challenges for farmer livelihoods. This research proposes an innovative approach using recurrent neural networks (RNNs) to predict both minimum and maximum prices. By analyzing historical market data, these models can forecast potential price ranges, empowering farmers to make informed decisions about planting, harvesting, and sales strategies. This enhanced foresight helps farmers navigate market volatility and improve income stability. © 2024 IEEE.
