Vlfeat_py

A python wrapper for the functions in vlfeat. Its not a wrapper on the Vlfeat C API but rather a wrapper on the functions listed in the Vlfeat C API

Features

• Extracts out SIFT Keypoints and Descriptors for an image
• Extracts out Dense SIFT Keypoints and Descriptors for an image
• Extracts the Region seeds and the frames for an MSER filter in an image

Quick Start

Installation

To install the package, run the following command

pip install -e git+https://github.com/lucasace/vlfeat_py.git#egg=vlfeat_py

Usage

To apply any of the supported descriptors for example SIFT, you can use the following code

import cv2
import vlfeat_py as vl

img = cv2.imread("path/to/image.jpg", cv2.IMREAD_GRAYSCALE)
[sift_keypoints, sift_descriptors] = vl.sift_desc(img)

Supported Descriptors

SIFT

[sift_keypoints, sift_descriptors] = vl.sift_desc(img)

Dense SIFT

[dense_sift_keypoints, dense_sift_descriptors] = vl.dsift_desc(img, np.array([0, 0, img.shape[0], img.shape[1]]))

MSER

[region_seeds, frames] = vl.mser_desc(img)

HOG

hog_desc = vl.hog_desc(img, 32)

LBP

lbp_desc = vl.lbp_desc(img, 32)
