This paper deals with identifying a writer from his/her offline handwriting. In a multilingual country where a writer can scribe in multiple scripts, writer identification becomes challenging when we have individual handwriting data in one script while we need to verify/identify a writer from handwriting in another script. In this paper such an issue is addressed with two scripts: English and Bengali...
We consider the problem of joint modeling of videos and their corresponding textual descriptions (e.g. sentences or phrases). Our approach consists of three components: the video representation, the textual representation, and a joint model that links videos and text. Our video representation uses the state-of-the-art deep 3D ConvNet to capture the semantic information in the video. Our textual representation...
We present a method for learning discriminative filters using a shallow Convolutional Neural Network (CNN). We encode rotation invariance directly in the model by tying the weights of groups of filters to several rotated versions of the canonical filter in the group. These filters can be used to extract rotation invariant features well-suited for image classification. We test this learning procedure...
Micro-expression recognition is a challenging task in computer vision field due to the repressed facial appearance and short duration. Previous work for micro-expression recognition have used hand-crafted features like LBP-TOP, Gabor filter and optical flow. This paper is the first work to explore the possible use of deep learning for micro-expression recognition task. Due to the lack of data for...
In this paper, we focus on the text/non-text classification problem: distinguishing images that contain text from a lot of natural images. To this end, we propose a novel neural network architecture, termed Convolutional Multi-Dimensional Recurrent Neural Network (CMDRNN), which distinguishes text/non-text images by classifying local image blocks, taking both region pixels and dependencies among blocks...
