چکیده
Sistemi Informativi LS 2 One image is worth 1,000 words… Undoubtedly, images are the most widespread MM data type, second only to text data Thus, it's not surprising that most efforts related to MMDB's have concentrated on images, in particular: Automatic extraction of features Similarity measures Indexing … Thus, let's move to see which are some basic features of images…

Color Image Segmentation using FCM Clustering Technique in RGB, L*a*b, HSV, YIQ Color spaces
Image segmentation is the important task for image analysis and understanding it. The segmentation of color image is challenging task in the image analysis process. Segmentation of color images gives more information than gray scale image. This paper performs segmentation of color image in different color spaces, as segmentation of RGB color image not always gives better segmentation results al...
متن کاملA novel RGB Fourier transform-based color space for optical microscopic image processing
This paper presents an IF1F2 color space for describing colors in microscopic images. Unlike the classical color spaces that treat the R, G, and B (RGB) components of a pixel’s color as independent elements, the proposed color space treats RGB as a sampled spectral signal, called a RGB signal. Then, based on the Fourier spectrum analysis of the RGB signal, the 1-D discrete Fourier transform is ...
متن کاملApproaches to color and texture based image classification
A Gabor filtering method for texture based classification of color images is presented. The algorithm is robust and can be used with different color representations. It involves a filter selection process based on texture smoothness. Unichannel and interchannel correlation features are computed. Two types of color representations have been considered: (1) computing chromaticity values from xyY,...
متن کاملFace detection using a hybrid approach that combines HSV and RGB
The concept of face detection is very useful in many applications like face recognition, facial expression recognition, face tracking, facial feature extraction, gender classification, identification system, document control and access control, clustering, biometric science, human computer interaction (HCI) system, digital cosmetics and many more [1]. In literature [2][10] there are many well-k...
متن کاملColor Image Enhancement by Histogram Equalization in Heterogeneous Color Space
This paper presents a luminosity conserving and contrast enhancing histogram equalization method for color images. The histogram equalization is one of the ordinary methods employed for enhancing contrast in TV and images for consumer electronics where unwanted subjective deterioration are frequently occur. Although there have been many solutions to overcome the drawback of histogram equalizati...
متن کاملHistogram-Based Color Image Retrieval
In this project, six histogram-based search methods are investigated in two different color spaces, RGB and HSV. Histogram search characterizes an image by its color distribution, or histogram but the drawback of a global histogram representation is that information about object location, shape, and texture is discarded. Thus this project showed that images retrieved by using the global color h...
