BezierAlign is a feature sampling method used for recognizing arbitrarily-shaped text in images. It takes advantage of the parameterization nature of a compact Bezier curve bounding box to achieve better accuracy in detecting and recognizing text, compared to other sampling methods.
What is Bezier Curve?
Bezier curve is a mathematical curve used in computer graphics, where the curve is defined by a series of control points. These control points can define any shape, such as a text box in an i
Overview of Deformable Position-Sensitive RoI Pooling
Deformable Position-Sensitive RoI Pooling is a deep learning technique used in computer vision to improve the accuracy of object detection in images. It is an extension of another technique called PS RoI Pooling, which stands for Position-Sensitive Region of Interest Pooling.
The purpose of RoI pooling is to take a set of fixed-size feature maps and align them with an arbitrary set of regions of interest (RoIs) within an image. The goal is
What is Deformable RoI Pooling?
Deformable RoI Pooling is a method used in object detection in computer vision that allows for better part localization in objects with different shapes. It involves adding an offset to each bin position in the regular bin partition of the RoI Pooling, enabling adaptive part localization.
RoI stands for Region of Interest, which is a rectangular region in an image that contains an object of interest. RoI Pooling is a method used to extract a fixed-length feature
If you're interested in computer vision and deep learning, you may have come across the term "GRoIE." This technology is an RoI (Region of Interest) extractor that aims to improve upon existing methods by selecting multiple layers from a feature pyramid network (FPN).
What is an RoI Extractor?
An RoI extractor is a key component in object detection, which is a type of computer vision that involves localizing and classifying objects in images or videos. The extractor's job is to take an input
Understanding Position-Sensitive RoI Pooling Layer
If you're new to the world of computer vision and deep learning, you may have come across jargons such as "position-sensitive RoI pooling layer". While it may sound intimidating at first, this layer is a crucial component of object detection and localization algorithms that allow machines to recognize and classify objects within an image or video.

Understanding Position-Sensitive RoIAlign
If you’re interested in object detection and want to be able to pinpoint where an object is located within an image, you need to be familiar with an algorithm called Region of Interest (RoI) pooling. RoI pooling is used in many state-of-the-art object detection systems, such as Faster R-CNN and Mask R-CNN. RoI pooling is the algorithm that allows for the selective alignment of an image segment, known as a region of interest (RoI).
RoI pooling takes a l
Precise RoI Pooling: An Overview
Precise RoI Pooling (PrRoI Pooling) is a feature extractor that is designed to identify and extract a region of interest (RoI) in an image. RoI pooling is a technique that first segments an image into different regions and then takes a feature map as input, which is then used to further extract the features from the identified RoI. PrRoI pooling is a significant improvement over traditional RoI pooling methods and is used in several modern computer vision applic
RoIAlign: Extracting Accurate Region of Interest Features
Region of Interest Align (RoIAlign) is a computer vision operation that extracts small feature maps from regions of interest (RoIs) in object detection and segmentation tasks. This technology accurately aligns the extracted RoI features with the input to improve precision and reduce errors.

RoI Pooling was the previous method used for extracting RoI features. However, it can produce harsh quantization of the ex
What is RoIPool and How Does It Work?
RoIPool, short for Region of Interest Pooling, is a powerful operation used in various computer vision tasks, including detection and segmentation models. It is designed to extract features from small regions within an image and process them to perform classification and regression tasks on the input image.
In RoIPool, a small feature map of size, for example, 7x7, is extracted from each region of interest (RoI). An RoI is a candidate box that encloses an
Region of Interest Warping, also known as RoIWarp, is a technique used in the field of computer vision that allows for more precise and flexible object detection. It is a form of RoIPool, a method that is commonly used in deep learning models for object recognition tasks. RoIWarp differs from RoIPool by being differentiable with respect to the box position, which allows for more accurate and efficient processing of images.

RoIWarp is made up of two layers—a RoIWarp layer and
What is Temporal ROIAlign?
Temporal ROIAlign is a technique for extracting features from multiple frames in a video to enhance object detection and tracking. This technique works by analyzing the feature maps of each frame and selecting the most similar features from other frames for a given object proposal in the current frame. This helps to improve the accuracy of object detection and tracking in videos.

Voxel RoI Pooling is an algorithm in computer vision which extracts region of interest (RoI) features directly from voxel features for further refinement. It is used to detect and classify objects in three-dimensional images or videos by dividing a region proposal into a regular sub-voxel grid. This grid is used to group neighboring voxels and create an aggregated feature vector that is used to identify the RoI features.
