Image Retrieval Using Different Distance Methods and Color Difference Histogram Descriptor for Human Healthcare

Abstract

As multimedia technology is developing and growing these days, the use of an enormous number of images and its datasets is likewise expanding at a quick rate. Such datasets can be utilized for the purpose of image retrieval. This research focuses on extraction of similar images established on its different features for the image retrieval purpose from huge dataset of images. In this paper initially, the query image is searched within the available dataset and, then, the color difference histogram (CDH) descriptor is employed to retrieve the images from database. The basic characteristic of CDH is that it counts the color difference stuck among two distinct labels in the L ∗ a ∗ b ∗ color space. This method is experimented on random images used for various medical purposes. Various unlike features of an image are extracted via different distance methods. The precision rate, recall rate, and F-measure are all used to evaluate the system’s performance. Comparative analysis in terms of F-measure is also made to check for the best distance method used for retrieval of images.

[Retracted] Optimized CNN‐Based Recognition of District Names of Punjab State in Gurmukhi Script

“…For the recognition, a Holistic approach is used instead of Analytical approach [3]. In the Holistic approach, word for the recognition is not divided into individual characters instead a complete word is recognized whereas in Analytical approach, segmentation of word into characters is done [4]. As Gurmukhi being the cursive handwriting and characters in the word are usually written close to each other, recognition of such words using Analytical approach does not generate good recognition results.…”

Transfer learning-based modified inception model for the diagnosis of Alzheimer's disease

“…The images are filtered with the help of kernels, as given in Table 5 as it displays the feature-visualized images of each convolutional layer (Chugh et al, 2022 ; Dhiman et al, 2022 ). It displays the first and last feature-visualized images for every convolutional layer (Sharma et al, 2022a , b ).…”

Segmentation and Classification of Encephalon Tumor by Applying Improved Fast and Robust FCM Algorithm with PSO-Based ELM Technique

“…As we know that particle swarm optimization is an optimization technique [ 44 ], which can optimize a problem by repeatedly testing to enhance a candidate solution with relation to a given measure of quality [ 45 ]. Basically, the design process is based on the manner of birds, so that they can exchange the information by swarming behavior [ 46 , 47 ].…”
