What is an RFP?
An RFP or Recursive Feature Pyramid is a type of network used to enhance object detection. It builds on top of Feature Pyramid Networks (FPN) by adding extra feedback connections from the FPN layers into the backbone layers. This recursive structure boosts performance and speeds up training by bringing features that receive gradients from detector heads back to the low levels of the backbone.

What is Reference-based Super-Resolution?
Reference-based Super-Resolution is a technique that helps to recover high-resolution images using external images as a reference. Essentially, this technology utilizes the rich textural content of the reference image to produce a superior quality image that has an enhanced resolution. This method can be especially useful in enhancing images that are blurry or pixelated, and it can help to optimize the display of images for a more professional and visua
Overview of Reference-Based Video Super-Resolution
Reference-based video super-resolution (RefVSR) is a technology used to enhance the resolution of a video using a reference video. The primary objective of RefVSR is to reconstruct a high-resolution video from a low-resolution video with the assistance of a reference video. This method is an extension of the reference-based super-resolution (RefSR) technique, which can be used to enhance the resolution of images.

Referring video object segmentation is a technique used in computer vision to separate and identify objects in a video using written or spoken language expressions as a reference point. Unlike traditional object segmentation techniques used in videos, the newly developed method identifies and segments objects using language expressions. This technology has several applications, ranging from surveillance to augmented reality and robotics.
Background
Object segmentation involves identifying and
Reformer is an architecture that has been developed to make transformer-based models more efficient. This model replaces dot-product attention with locality-sensitive hashing, making the process more efficient. The complexity is reduced from O($L^2$) to O($L\log L$), where $L$ is the length of the sequence. Furthermore, the use of reversible residual layers allows for the storage of activations only once in the training process instead of $N$ times, where $N$ is the number of layers.

Introduction to R-FCN
R-FCN or Region-based Fully Convolutional Networks is a type of region-based object detector. Unlike previous object detectors where a costly per-region subnetwork is applied hundreds of times, R-FCN is a fully convolutional network, with almost all computation shared on the entire image.
How R-FCN Works
R-FCN achieves this by utilising position-sensitive score maps. These score maps are used to address a dilemma between translation-invariance in image classification an
What is an RPN?
An RPN, which stands for Region Proposal Network, is a kind of neural network that predicts both the bounds and the likelihood of an object in an image. Essentially, the RPN tries to identify where objects are in an image by suggesting a region of the image that corresponds to an object. This is an important task in many computer vision applications, including object detection, segmentation and tracking.
How does an RPN work?
An RPN works by using convolutional neural network
Introduction to RegionViT
RegionViT is a new method for converting images into tokens that can be used for image classification and object detection. This method involves splitting an image into two types of tokens: regional and local. These tokens are created through a convolution process with different patch sizes. The regional tokens are made up of patches that cover 28x28 pixels while the local tokens are made up of patches that cover 4x4 pixels. Each regional token covers 7x7 local tokens

Overview of RegNetX
RegNetX is a network design space that creates simple, regular models with specific parameters. The three parameters are the depth (d), initial width (w_0), and slope (w_a). The design space generates a different block width (u_j) for each block (j) that is less than the depth (d). The key restriction of RegNetX models is that there is a linear parameterization of block widths. This means that the design only contains models with this linear structure.

An autoencoder is a type of neural network that is trained to learn a compressed representation of data, typically for the purpose of dimensionality reduction or feature extraction. Essentially, it learns to encode the input data into a low-dimensional representation and then decode it back into its original form. By doing so, it can identify patterns and correlations within the data that may not be readily apparent in the raw data.
