Question: What is selective search algorithm?

Selective Search is a region proposal algorithm used in object detection. It is designed to be fast with a very high recall. It is based on computing hierarchical grouping of similar regions based on color, texture, size and shape compatibility.

What is the best algorithm for object detection?

How does R-CNN work?

In Fast RCNN, we feed the input image to the CNN, which in turn generates the convolutional feature maps. Using these maps, the regions of proposals are extracted. We then use a RoI pooling layer to reshape all the proposed regions into a fixed size, so that it can be fed into a fully connected network.

Is Yolo better than RCNN?

YOLO stands for You Only Look Once. In practical it runs a lot faster than faster rcnn due its simpler architecture. Unlike faster RCNN, its trained to do classification and bounding box regression at the same time.

Which is faster Yolo or SSD?

SSD, a single-shot detector for multiple classes thats quicker than the previous progressive for single-shot detectors (YOLO), and considerably a lot of correct, really as correct as slower techniques that perform express region proposals and pooling (including quicker R-CNN).

Is CNN better than LSTM?

2018 showed their flavor of CNN can remember much longer sequences and again be competitive and even better than LSTM (and other flavors of RNN) for a wide range of tasks.
