The core message of this paper is that the authors propose a novel framework called CRFormer that deep integrates language representation to address the problem of language information distortion during the semantic propagation process in referring image segmentation.
Sammanfattning
The paper introduces CRFormer, a model that iteratively calibrates multi-modal features in the transformer decoder to address the challenge of efficiently propagating fine-grained semantic information from textual features to visual features in referring image segmentation.
The key highlights are:
-
The authors generate multiple language queries representing various emphases and detailed semantic information to mitigate natural distortion during the decoder propagation process.
-
They design a novel Calibration Decoder (CDec) that can continuously calibrate the language information by generating new language queries in each decoder layer.
-
They introduce a Language Reconstruction Module and a reconstruction loss to evaluate the distortion degree of language information after continuous correction, which can further prevent the language information from being lost or distorted.
-
The experiments show that the proposed CRFormer achieves new state-of-the-art results on three referring image segmentation datasets, demonstrating the effectiveness of the deep integrated language approach.
Statistik
"The primary challenge lies in the efficient propagation of fine-grained semantic information from textual features to visual features."
"Conventional transformer decoders can distort linguistic information with deeper layers, leading to suboptimal results."
"We start by generating language queries using vision features, emphasizing different aspects of the input language."
"We propose a novel Calibration Decoder (CDec) wherein the multi-modal features can iteratively calibrated by the input language features."
"We introduce a Language Reconstruction Module and a reconstruction loss to further prevent the language information from being lost or distorted."
Citat
"As the layer count in the conventional Transformer decoder increases, the vision features of the query continuously fuse with language features, iteratively forming new multi-modal features. Concurrently, the language features of the key and value remain unaltered, thereby impeding the propagation process."
"In the standard Transformer decoder, as the depth of the decoder layers increases, there is a potential loss or distortion of crucial language information."
