Abstract

This research is entitled Analysis of Face Detection With Accessories On The Head Using Haar Cascade In Image Processing. The problem faced is how accurate the haar cascade algorithm is in detecting faces with accessories on the head, whether the haar cascade algorithm can still detect faces even though there are accessories that are felt around the face, therefore a study was conducted on face detection with accessories on the head using the haar cascade algorithm in several facial conditions such as facial angles and in several lighting conditions in the detection process. This study aims to analyze the accuracy of the haar cascade algorithm in detecting faces with accessories on the head, whether haar cascade can still detect faces even though there are accessories around the face that block, and 20 facial data sets were taken with a real-time laptop camera. The facial data obtained was taken in several places such as campus areas, houses and boarding houses and with various lighting conditions. From 20 face data taken in real time, researchers obtained 2 face data that were not detected due to poor lighting when taking face data and obtained 18 face data that were successfully detected even though using accessories around the face and it is certain that haar cascade has very good accuracy in detecting faces even though they were blocked by accessories. The testing methods applied are precision, recall and accuracy for calculating the results obtained. The results of the study obtained a precision of 100%, recall 90% and accuracy of 90%.

Abstract

Air merupakan sumber daya alam yang memiliki peranan penting dalam kehidupan manusia, sehingga penilaian kualitasnya sangat diperlukan untuk memastikan kelayakan penggunaannya. Salah satu indikator fisik dalam mengevaluasi kualitas air adalah tingkat kejernihan yang dapat diamati melalui karakteristik warna. Namun, penilaian secara visual sering bersifat subjektif, sehingga diperlukan pendekatan yang lebih objektif melalui pengolahan citra digital. Penelitian ini bertujuan untuk menganalisis distribusi intensitas warna pada citra air menggunakan metode histogram RGB. Metode yang digunakan meliputi akuisisi citra, pra-pemrosesan, ekstraksi fitur warna, serta analisis distribusi intensitas piksel pada kanal Red, Green, dan Blue. Nilai rata-rata intensitas RGB juga dihitung untuk menentukan karakteristik warna dominan pada setiap sampel. Dataset dikategorikan menjadi tiga kelompok, yaitu air jernih, agak keruh, dan keruh. Hasil menunjukkan bahwa air jernih memiliki distribusi histogram RGB yang seimbang dan saling berhimpit, sedangkan air agak keruh menunjukkan pergeseran warna secara bertahap. Air keruh memperlihatkan dominasi kanal warna tertentu dengan penyebaran histogram yang lebih luas. Hasil penelitian ini menunjukkan bahwa analisis histogram RGB mampu memberikan gambaran kuantitatif distribusi intensitas warna air dan dapat digunakan sebagai pendekatan awal dalam mengidentifikasi tingkat kejernihan air secara objektif

Abstract

Archaic image restoration faces significant challenges due to complex degradation in the form of blurring and attenuation of extreme luminance (low-light) that obscure the identity of historical subjects. This study constructs a new paradigm through the Face-Centered Enhancement mechanism based on GFPGAN to reconstruct high-fidelity facial features in visual archives from the Bengkulu Museum, Bung Karno's Exile House, and Fort Marlborough. The novelty of this study lies in the integration of a feature enhancement module capable of performing adaptive deconvolution specifically on the face area to mitigate stochastic hallucinations in the GAN latent space, thus balancing lighting restoration without distorting the authenticity of the original character of historical figures. Quantitative evaluation of 50 images using a synthetic degradation scheme shows superior performance, where 95% of the data achieves SSIM ≥ 0.95 and MSE ≤ 0.01. This improvement in visual quality has direct implications for the efficiency of the OCR system in extracting document text and optimizing classification in digital archival information systems. Despite its dependence on high-performance computing, this method has proven effective in bridging the disparity between improving pixel quality and preserving historical integrity in national digital preservation efforts.

Abstract

By looking at student achievement, the educator in evaluating whether the teaching system used has been successfully accepted or not by the students being taught. Online learning media using a technology approach that is more appropriate to today's student learning systems than the conservative method of learning in class. In addition to class ranking positions, there are also student positions in the Parallel Class Ranking (RKP). The list of RKP positions contains the names of students, sorted by the highest total score for each grade level and announced on the school bulletin board. The Simple Multi Attribute Rating Technique (SMART) method is a multi-criteria decision-making method based on the theory that each alternative consists of a number of criteria that have a value and each criterion has a weight to describe how important its value is compared to other criteria. So the problem is how to implement the smart method for ranking. With the aim of providing student ranking information using the smart method (simple multi attribute rating technique) based on student assessments. It is hoped that this implementation can become a reference not only for stone sales decisions based on rankings but can apply online and structured assessments.
