يقع هذا البحث في مجال معالجة الصور عموماً، و معالجة صور السجاد خصوصاً، بما لها من ميزات و بما عليها من قيود. يهدف هذا البحث إلى اختزال عدد ألوان صورة سجادة مأخوذة بواسـطة الماسـح الضوئي، و الحصول على صورة تحوي الألوان الخمسة التي كانت موجودة أصلاً في الـصورة المـصدر بعدما تحولت نتيجة المسح الضوئي إلى صورة تحوي 16 مليون لون، مع الحرص علـى عـدم حـدوث تشوه في الصورة الناتجة، أي الحصول على جميع الأشكال الموجودة في الصورة الأصلية آلياً دون تدخل المستخدم. طورت لهذا الغرض خوارزمية في نظام CDS) System Design Carpet) -و هو نظام مطور محليـاً خصيصاً لأغراض تخدم عملية حياكة السجاد في المؤسسة العامة للصناعات النسيجية في سورية- و لكن ما تزال نتائج تطبيق الخوارزمية غير مرضية، حيث تحوي الصورة الناتجة تشوهات تدفع مستخدم النظام للاستعانة بأحد برامج معالجة الصور (Photoshop على سبيل المثال) لتصحيحها، مما يستغرق مدة تصل إلى قرابة الأسبوعين في بعض الحالات. قمنا في هذا البحث بدراسة عملية التحويل ضمن نظام CDS من جهة، و دراسة خوارزميـات تكمـيم الألوان المطورة في مخابر البحث المختصة المشهورة عالمياً في مجال معالجة الصور من جهة أخـرى، تم تطبيق هذه الخوارزميات على صور السجاد و إجراء بعض التعديلات أحياناً، و مقارنة النتائج و اقتـراح حلٍ أفضل للمسألة المطروحة (مسألة التحويل).
The topic of this research aims at minimizing carpet image color number (acquired by a scanner) from 16 million colors to 5 colors, in order to restore the shapes of the original image automatically without distortions. For this purpose an algorithm was developed for the application called CDS (Carpet Design System)- which is an application developed locally for use in sewing carpets in General Institution of Texture Factory in Syria-, but the results are still not acceptable, because the resulting images have a lot of distortions, and they need some processing using an image processing application (ex. Photoshop). This task needs more than tow weeks. In this research work, we study the CDS algorithm, and other color quantification algorithms, developed in research laboratories specialized in image processing. We apply this algorithms on carpet images, after doing the necessary modifications for tuning and adapting to our special problem. Finally we compare the results, and suggest the best solution for the problem.

This paper introduces an algorithm to find out value of number for industrial counter
from image of pulse plan. that is achieved by image processing of pulse plan for counter,
pulse plan has been segmentation, and alternating times and type are det
ected. Type of
alternating time means that if they are rising edge, that has zero value, or if they are falling
edge, that has one value. Number of total edge is calculated for both type rising or falling.
Number of value for counter is calculated by dividing number of edges on two. Two type
of pulse plans are processed, the first one is pulse plans have empty pulse signals (pulse
contains white pixels) and the second one is pulse plans have filled pulse signals (pulse
contains nonwhite pixels). Proposal algorithm is developed to process two types.
Programming interface is designed using MatLab for proposal algorithm. Three
image of pulse plans are applied on this programming interface. It gives perfect results, by
rate 100% and value of number for industrial counter is extracted for plans contains empty
pulse or filled one. Rate of That is because used neoural neworked has 100% recogition
rate, and proposal algorithm can find number of edges by 100% rate.
The basic step in this algori thm is determining the number of clusters
(K) then calculating the distance between each cluster
center and the elements of images to join each element
to the closest cluster depending on threshold distance.
This research suggests a new method that aims to verify the manual signature image which is written by person, and specify whether this signature back to this person or that forged signature. This was done by extracting geometric features of the sign
ature image and applying statistical functions on them as a way to verify the signature of that person.
The features from the signature image have been extracted on many stages so a signature image has been transformed from the gray scale to binary format, and then extracting the statistical features from the original signature image which is the maximum value from the most repeated values in the ones' coordination line that determine the signature shape, in addition to the number of ones which also determine the signature shape. Finally two ranges have been identified for the values accepted for original signature image. By the same way, statistical features have been extracted from the foreign signature image and tested if they aggregate within the specified domain of acceptable values. This research also includes the results of the proposed approach that compared with the previous methods in this scope. The proposed method has been tested to the data base consisting of 16200 signatures back to 300 persons, and as a result the signature image has been verified with a good percentage.

The entry of computer to many areas, such as medical field, led to develop new
technique that has led to the prosperity of these areas, and helped doctors to detect and
diagnose diseases accurately and credibility, where the experience of the docto
r in addition
to the accuracy of computer lead to access to the credibility of high patient and save
human lives.
A new approach for cardiac diseases detection and classification in ECG signals
images is proposed using Adaptive Neuro Fuzzy Inference System ANFIS.
The proposed approach is applied on database containing (147) ECG images,
each of them accompanied with its medical report. The medical reports were used to
validate the detection and classification.
The proposed method achieved a relatively high accuracy (97%) in detection and
classification processes.
The proposed approach is developed using MATLAB, and based on its libraries,
image processing, neural network and fuzzy logic.
Modern web content - news articles, blog posts, educational resources, marketing brochures - is predominantly multimodal. A notable trait is the inclusion of media such as images placed at meaningful locations within a textual narrative. Most often,
such images are accompanied by captions - either factual or stylistic (humorous, metaphorical, etc.) - making the narrative more engaging to the reader. While standalone image captioning has been extensively studied, captioning an image based on external knowledge such as its surrounding text remains under-explored. In this paper, we study this new task: given an image and an associated unstructured knowledge snippet, the goal is to generate a contextual caption for the image.
