attention object detection

January 23, 20210

of the IEEE Conference on Computer Vision and Pattern Consequently, we decided to revisit the concept of a saliency-guided region proposal network, armed with deeper insights into its biological mechanisms. A primary source of these overheads is the exhaustive The concept of an ‘object’, apropos object-based attention, entails more than a physical thing that can be seen and touched. Video object detection plays a vital role in a wide variety of computer vision applications. Consequently, detection time, defined as the average time taken by the model to generate a predicted saliency map based on each of the test images, and floating-point operations (FLOPs), defined in [39], were measured. ∙ Journal of Computer Vision (IJCV), J. Hosang, R. Benenson, P. Dollár, and B. Schiele, “What Makes for Finally, a fully convolution layer with a. kernel and sigmoid activation function outputs a pixel-wise probability (saliency) map the same size as the input, where larger values correspond to higher saliency. Therefore, the pursuit of a deeper understanding of the mechanisms behind saliency detection prompted a thorough investigation of the visual neuroscience literature. However, with the resurgence of deep learning [23], two-stage detectors quickly came to dominate object detection. 1097–1105, Curran This figure panel compares the number of regions (red boxes) typically classified as containing background or objects by state-of-the-art object detection models with our method. ∙ Remove moving objects to get the background model from multiple images, Retrain object detection model with own images (tensorflow).

ICRA 2008. classification of typically 10^4-10^5 regions per image. The model generates a binary object mapping from a given input, which can then be compared with corresponding groundtruth labels. However, two recent papers by independent research teams [19, 21] converged on the claim that the saliency map is actually generated in a significantly smaller and more primitive structure called the superior colliculus (SC). Moreover, the model uses two to three orders of magnitude fewer Resolutions below 16 or above 512 pixels were deemed unnecessary for our investigation. There are many ways object detection can be used as well in many fields of practice. A problem with this approach is that not all objects of interest are detected; just objects that grab human attention, which is inadequate for general object detection. With the rise of deep learning, CNN-based methods have become the dominant object detection solution. 11/19/2018 ∙ by Shivanthan Yohanandan, et al.

Notes in Computer Science, pp. This is similar to salience detection models trained on human eye-tracking datasets where fixated objects in an image are assigned the same groundtruth class label despite coming from semantically different object categories. In general, if you want to classify an image into a certain category, you use image classification.

RGCs express color opponency via longwave (red), medium-wave (green), and shortwave (blue) sensitive detectors, and resemble a Laplacian probability density function (PDF). Since salience can be thought of as a single class, the SC essentially behaves as a binary classifier [11]. Like every other … Associates, Inc., 2012. Therefore, it seems reasonable to hypothesize that the optimal retinocollicular compression resolution depends on the dataset. (C. Cortes, N. D. Lawrence, D. D. Lee, M. Sugiyama, and R. Garnett, eds.

Making statements based on opinion; back them up with references or personal experience. A promising future direction to explore is an optimization algorithm that automatically learns the optimal input resolution (i.e. The retina then segregates information from this image into different visual pathways. Their main motivation was that a saliency map, generated non-exhaustively, could highlight regions containing objects, which can then be proposed to an object-category classifier, thereby ignoring background regions altogether and potentially saving thousands of unnecessary classifications. Unfortunately, none have improved the speed or efficiency over state-of-the-art models. computations than state-of-the-art models and consequently achieves inference I have followed show-attend-and-tell (caption generation).

These approaches are efficient but lack of holistic analysis of scene-level context. In contrast, object detection in biological vision systems is extremely efficient owing to the mechanisms behind salience detection and selective attention [11].

Different from semantic segmentation, instance segmentation and other tasks requiring dense labels, the purpose of salient object detection (SOD) is to segment the most visually distinctive objects in a given natural image , .As an important problem in computer vision, SOD has attracted more and more researchers’ attention. Deep learning object detectors achieve state-of-the-art accuracy at the This study provides two main contributions: (1) unveiling the mechanism behind speed and efficiency in selective visual attention; and (2) establishing a new RPN based on this mechanism and demonstrating the significant cost reduction and dramatic speedup over state-of-the-art object detectors. Object detection is a challenging computer vision task that involves predicting both where the objects are in the image and what type of objects were detected. GitHub Source Team Size: 3.

Why are two 555 timers in separate sub-circuits cross-talking? Such an arrangement has the effect of significantly reducing the visual search space of objects and regions of interest [22], , so that a relatively small and simple neural network suffices for computing and generating a saliency map. In view of the above problems, a multi-attention object detection method (MA-FPN) based on multi-scale is proposed in this paper, which can effectively make the network pay attention to the location of the object and reduce the loss of small object information.

Therefore, high-resolution details about objects, such as texture, patterns, and shape, seem irrelevant and superfluous. The proposed superior colliculus region proposal network (SC-RPN, Figure 4) simulates partial functionality of the superior colliculus by treating all objects and regions of interest or relevance as salient, and subsequently generating a spatial map locating them. Given that most of Nevertheless, while two-stage detectors achieved unprecedented accuracies, they were slow. salient, while ignoring irrelevant stimuli such as background. These saliency-based approaches were inspired by the right idea; however, their implementations may not have been an accurate reflection of how saliency works in natural vision.

In this paper, we present an "action-driven" detection mechanism using our "top-down" visual attention model. A. Figure 8 complementarily echos the significant reduction in computational overheads by showing that the SC-RPN is capable of generating the complete set of region proposals at 500 frames/s. As pioneered in the Selective Search work [24], the first stage generates a sparse set of ideally object-only candidate proposals while filtering out the majority of negative locations [25], while the second stage classifies the proposals into object-category classes. -C). Secondly, an object can be simply defined as something that occupies a region of visual space and is distinguishable from its surroundings. Song, A. G. Dyer, and D. Tao, “Saliency Preservation in Neural Information Processing Systems 25. Therefore, computationally, we can think of objects and regions of interest in the visual environment as being our positive (salient) class, and everything else as background, which is analogous to a training dataset containing images with background and positively labelled object regions. Concretely, we had training datasets Di with i∈{1,2,3,4,5} of square images of resolution r∈{16,32,64,128,256,512}2, Ir (see Figure 5-A), with associated labels LrI representing the instances of k objects present in I, with k⊆C, where C is the set of all positive object classes. Most of these improvements are derived from using a more sophisticated convolutional neural network. The SC then aligns the fovea to attend to one of these regions, thereby sending higher-acuity, e.g. On the other hand, it takes a lot of time and training data for a machine to identify these objects. Hence, we conducted further research to determine whether any studies specifically investigated the neural circuitry entering the SC from the eye via the retinocollicular (retina to superior colliculus) pathway, since we suspected that a relatively small proportion of information from the eye is used for computing saliency, based on a recent study hypothesizing that peripheral vision information was low-resolution and used for computing saliency [11]. 770–778, 2016.

An NVIDIA Tesla K80 GPU was used for training and inference. Fu, and A. C. Berg, We did not adopt other common evaluation metrics, such as mean average precision (mAP), since saliency map proposals may include overlapping objects, and hence, regions containing multiple objects. Figure 7 shows the dramatic reduction in computation cost from 109 FLOPs at 512×512, which is representative of high-resolution input images used in most state-of-the-art detectors, to 107 FLOPs at 128×128 and 64×64. However, it is difficult to obtain a domain-invariant detector when there is large discrepancy between different domains. This plot shows mean inference times for SC-RPNs trained and tested on each of the 5 dataset at 6 different image resolutions. 20 Finally, to determine (3) and (4), we needed to measure the SC-RPN’s computational costs and inference times across all 6 input resolutions.
