Mask R-CNN: A Comparative Study On Improvements In Object Detection And Segmentation

Abstract

Over the years there has been an increasing demand for image recognition as the world is moving towards a digital space. With the increasing demands, the application of Mask RCNN and expanded algorithms based on segmentation and YOLO have seen a major rise in the last 5 years. So the accuracy of the models has improved slightly since most projects take different approaches to the different datasets and have different metrics of Evaluation. By cross-referencing these approaches, a trend is observed that leads to higher success with the implementation of models using the hyperparameters and extra layers that have been added to the Mask RCNN in sequences. In this paper, the different approaches taken by different researchers are explored to understand how the implementations have progressed over the last half of the decade. In our research, we have studied & analyzed 50 papers and found that the majority of papers were using the COCO dataset for training purposes with a specified set of hyper-parameters to measure the accuracy, performance, and memory consumption. The experiment findings were presented to suggest suitable RCNN architecture based on application or hardware attributes.

Colloidal Manipulation through Plasmonic and Non‐plasmonic Laser‐Assisted Heating

“…Recently, long working distance, low‐power optothermoelectric trapping, and spectroscopic studies of fluorescent nanodiamonds (FNDs) are demonstrated by drop casting the chemically synthesized plasmonic nanostructures such as gold nanosphere and silver nanowire (AgNW) on the glass coverslip instead of lithographically prepared gold film or nanoantennae. [ 136 ] The excitation of an anchored single gold sphere (400 nm) by a 532 nm laser using a low NA objective (0.5) quickly traps the FND at a laser intensity down to 12.2 µW µm −2 . The trapping with AgNW with an average diameter of 350 nm requires a minimum intensity of 85 µW µm −2 when the laser polarized along the nanowire to excite the plasmons.…”

“…A similar approach in Figure 5e was applied, the Opto-thermo-electric (OTE) technique facilitated by surfactant, where the same 532 nm laser was used for resonant excitation of drop-casted Ag nanowires/Au nanoparticles for trapping and exciting NDs. [87] The force due to OTE is higher compared to optical trapping; hence less laser power is required. There will not be quenching of fluorescence compared to previous techniques, as no IR was used.…”

“…However, its use in crop protection is just in its early days. [1] Nanoparticles or nanomaterials are substances of nanometer sizes (generally between 1 and 100 nm). Over many decades, nanotechnology and nanomaterials have been employed successfully and safely in various fields like medicine, environmental science, and agriculture.…”
