Digital and real-world researchers asking all the right questions. Original research, best-in-class segmentation and sought-after sources. Proven methodology that brings insight into focus.

Partners with power Google, Facebook, and B2B platform partners. Data players expected and unexpectedly necessary. We propose ContextNet, a new deep neural network architecture which builds on factorized convolution, network compression and pyramid representations to produce competitive semantic segmentation in real-time with low memory requirements.

ContextNet combines a deep branch at low resolution that captures global context information efficiently with a shallow branch that focuses on high-resolution segmentation details. We analyze our network in a thorough ablation study and present results on the Cityscapes dataset, achieving Yu ECCV Existing semantic segmentation methods mostly rely on per-pixel supervision, unable to capture structural regularity present in natural images.

Instead of learning to enforce semantic labels on individual pixels, we propose to enforce affinity field patterns in individual pixel neighbourhoods, i. The affinity fields characterize geometric relationships within the image, such as "motorcycles have round wheels". We further develop a novel method for learning the optimal neighbourhood size for each semantic category, with an adversarial loss that optimizes over worst-case scenarios.

Unlike the common Conditional Random Field CRF approaches, our adaptive affinity field AAF method has no extra parameters during inference, and is less sensitive to appearance changes in the image. There are multiple branches with different dilate rates for varied pooling size, thus varying receptive field. The best single model is The sync batch normalization layer is implemented in Tensorflow see the code. The encoder part is constructed based on the concept of DenseNet, and a simple decoder is adopted to make the network more efficient without degrading the accuracy.

We pre-train the encoder network on the ImageNet dataset. Then, only the fine-annotated Cityscapes dataset training images is used to train the complete DSNet. The DSNet demonstrates a good trade-off between accuracy and speed. Asymmetric Depthwise Separable Convolution for Semantic Segmentation in Real-time Anonymous A lightweight and real-time semantic segmentation method for mobile devices.

The result is tested by multi scale and filp. The paper is in preparing. We will release our paper latter. The state-of-the-art scene parsing methods define the context as the prior of the scene categories e.

Such scene context is not suitable for the street scene parsing tasks as most of the scenes are similar. In this work, we propose the Object Context that captures the prior of the object's category that the pixel belongs to. We compute the object context by aggregating all the pixels' features according to a attention map that encodes the probability of each pixel that it belongs to the same category with the associated pixel.

Specifically, We employ the self-attention method to compute the pixel-wise attention map. Even though a contour is in general a one pixel wide structure which cannot be directly learned by a CNN, our network addresses this by providing areas around the contours. Based on these areas, we separate the individual vehicle instances. The former is computed from a standard CNN for semantic segmentation, and the latter is derived from a new instance-aware edge detection model.

To reason globally about the optimal partitioning of an image into instances, we combine these two modalities into a novel MultiCut formulation. The loss function encourages the network to map each pixel to a point in feature space so that pixels belonging to the same instance lie close together while different instances are separated by a wide margin.

Previously listed as "PPLoss". Adds an improved angular distance measure and a foveal concept to better address small objects at the vanishing point of the road.

Torr Computer Vision and Pattern Recognition CVPR We propose an Instance Segmentation system that produces a segmentation map where each pixel is assigned an object class and instance identity label this has recently been termed "Panoptic Segmentation".

Our method is based on an initial semantic segmentation module which feeds into an instance subnetwork. This subnetwork uses the initial category-level segmentation, along with cues from the output of an object detector, within an end-to-end CRF to predict instances. This part of our model is dynamically instantiated to produce a variable number of instances per image. Our end-to-end approach requires no post-processing and considers the image holistically, instead of processing independent proposals.

As a result, it reasons about occlusions unlike some related work, a single pixel cannot belong to multiple instances.

Efficient Urban Semantic Scene Understanding. Combines the following concepts: Conv-Deconv Grid-Network for semantic segmentation. Pyramid Scene Parsing Network. We used a new architecture for semantic image segmentation called GridNet, following a grid pattern allowing multiple interconnected streams to work at different resolutions see paper.

Deep segmentation network with hard negative mining and other tricks. The scale difference in driving scenarios is one of the essential challenges in semantic scene segmentation. Numerous deep learning applications benefit from multi-task learning with multiple regression and classification objectives. We propose a novel method based on convnets to extract multi-scale features in a large range particularly for solving street scene segmentation.

Most existing methods of semantic segmentation still suffer from two aspects of challenges: Semantic image segmentation, which assigns labels in pixel level, plays a central role in image understanding. Rather than offer the same marketing mix to vastly different customers, market segmentation makes it possible for firms to tailor the marketing mix for specific target markets, thus better satisfying customer needs.

Not all elements of the marketing mix are necessarily changed from one segment to the next. For example, in some cases only the promotional campaigns would differ. A market can be segmented by various bases, and industrial markets are segmented somewhat differently from consumer markets, as described below. A basis for segmentation is a factor that varies among groups within a market, but that is consistent within groups. One can identify four primary bases on which to segment a consumer market:.

Geographic segmentation is based on regional variables such as region, climate, population density, and population growth rate. Demographic segmentation is based on variables such as age, gender, ethnicity, education, occupation, income, and family status.
