Synchronizing Vision and Language: Bidirectional Token-Masking AutoEncoder for Referring Image Segmentation
Referring Image Segmentation (RIS) aims to segment target objects expressed
in natural language within a scene at the pixel level. Various recent RIS
models have achieved state-of-the-art performance by generating contextual
tokens to model multimodal features from pretrained encoders and effectively
fusing them using transformer-based cross-modal attention. While these methods
match language features with image features to effectively identify likely
target objects, they often struggle to correctly understand contextual
information in complex and ambiguous sentences and scenes. To address this
issue, we propose a novel bidirectional token-masking autoencoder (BTMAE)
inspired by the masked autoencoder (MAE). The proposed model learns the context
of image-to-language and language-to-image by reconstructing missing features
in both image and language features at the token level. In other words, this
approach involves mutually complementing across the features of images and
language, with a focus on enabling the network to understand interconnected
deep contextual information between the two modalities. This learning method
enhances the robustness of RIS performance in complex sentences and scenes. Our
BTMAE achieves state-of-the-art performance on three popular datasets, and we
demonstrate the effectiveness of the proposed method through various ablation
studies
Tiny Medicine: Nanomaterial-Based Biosensors
Tiny medicine refers to the development of small easy to use devices that can help in the early diagnosis and treatment of disease. Early diagnosis is the key to successfully treating many diseases. Nanomaterial-based biosensors utilize the unique properties of biological and physical nanomaterials to recognize a target molecule and effect transduction of an electronic signal. In general, the advantages of nanomaterial-based biosensors are fast response, small size, high sensitivity, and portability compared to existing large electrodes and sensors. Systems integration is the core technology that enables tiny medicine. Integration of nanomaterials, microfluidics, automatic samplers, and transduction devices on a single chip provides many advantages for point of care devices such as biosensors. Biosensors are also being used as new analytical tools to study medicine. Thus this paper reviews how nanomaterials can be used to build biosensors and how these biosensors can help now and in the future to detect disease and monitor therapies
