One of the various characteristics used to describe clay in a qualitative manner is porosity, as it is considered one of the properties that with \u201ckill or cure\u201d effectiveness. For this purpose, we use scanning electron microscopy images, as they are considered the most powerful tool for characterising the quality of the microscopic pore structure of porous materials. We present various existing methods of segmentation, as we are interested only in pore regions. The results show good matching between physical estimation and Voronoi diagram-based porosity estimation.<\/jats:p>","DOI":"10.1515\/jisys-2018-0191","type":"journal-article","created":{"date-parts":[[2019,12,24]],"date-time":"2019-12-24T04:02:12Z","timestamp":1577160132000},"page":"1226-1234","source":"Crossref","is-referenced-by-count":1,"title":["Clay-Based Brick Porosity Estimation Using Image Processing Techniques"],"prefix":"10.1515","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6131-8755","authenticated-orcid":false,"given":"Safa","family":"Jida","sequence":"first","affiliation":[{"name":"Department of Computer Sciences , Asia Team, Laboratory M2I, Faculty of Sciences and Techniques Errachidia , Errachidia 52000, Morocco"}]},{"given":"Hassan","family":"Ouallal","sequence":"additional","affiliation":[{"name":"Department of Fundamental and Applied Chemistry , Laboratory PCM, Faculty of Sciences and Techniques Errachidia , Errachidia , Morocco"}]},{"given":"Brahim","family":"Aksasse","sequence":"additional","affiliation":[{"name":"Department of Computer Sciences , Asia Team, Laboratory M2I, Faculty of Sciences and Techniques Errachidia , Errachidia 52000, Morocco"}]},{"given":"Mohammed","family":"Ouanan","sequence":"additional","affiliation":[{"name":"Department of Computer Sciences , Asia Team, Laboratory M2I, Faculty of Sciences and Techniques Errachidia , Errachidia 52000, Morocco"}]},{"given":"Mohamed El","family":"Amraoui","sequence":"additional","affiliation":[{"name":"Department of Physics , Faculty of Sciences Meknes, Moulay Ismail University , Meknes , Morocco"}]},{"given":"Mohamed","family":"Azrour","sequence":"additional","affiliation":[{"name":"Department of Fundamental and Applied Chemistry , Laboratory PCM, Faculty of Sciences and Techniques Errachidia , Errachidia , Morocco"}]}],"member":"374","published-online":{"date-parts":[[2019,2,23]]},"reference":[{"key":"2025120523362774264_j_jisys-2018-0191_ref_001","doi-asserted-by":"crossref","unstructured":"K.
