Abstract: There is provided a method and electronic device for generating high resolution peak action frame. The method includes receiving a low resolution (LR) image stream with high frame speed and a high resolution (HR) image stream with low frame speed and detecting at least one pose of at least one human in the LR image stream. The method further includes obtaining a LR peak action frame in the LR image stream based on the at least one pose and identifying a close HR frame from the HR image stream which is closest to the LR peak action frame. The method further includes fetching the close HR frame from the HR image stream which is closest to the obtained LR peak action frame or generating a HR peak action frame by blending the identified HR frame and the LR peak action frame.

Abstract: Embodiments herein provide a method for removing an artefact in a high resolution image by an electronic device (100). The method includes receiving the high resolution image comprising the artefact. Further, the method includes downscaling the high resolution image into a plurality of lower resolution images. Further, the method includes removing the artefact from the plurality of lower resolution images by applying at least one first machine learning model from a plurality of machine learning models on the plurality of lower resolution images. Further, the method includes generating a high resolution image free from the artefact by applying at least one second machine learning model from the plurality of machine learning models on an output from the at least one first machine learning model. The output from each of the machine learning model comprises a low resolution image free from the artefact.
